"The Being or Nature which philosophy sought to reach was thought ofThe religious language and the concepts of the pre-Socratics are not just relics of the pre-scientific way of thought, not yet outgrown, but the expression of their fundamental religious orientation. As Werner Jaeger says in his Theology of the Early Greek Philosophers,
as a worthier conception of the divine than that presented by the anthropomorphic gods." [3]
"Though philosophy means the death of the old gods, it is itself religion." [4]And this religion is a religion of Reason. This became explicit in the teaching of Socrates. Socrates lived and taught the ultimacy of Reason and was executed in 399 B.C. for nothing less than the crime of rationalism - an act of destroying the gods by reason. [5] But he was only substituting for faith in one set of gods faith in another god - Reason. Plato was inspired by his teacher Socrates to the same faith.
The divine, according to the Greek conception of reality, is that which is not subject to change, decay or death; the gods in Homer are "immortals." The divine, therefore, cannot be known through the senses because that which is known through the senses is a world characterized by change, decay or death. But since the objects of reason are always and everywhere the same, the divine can be known through reason. This eternal, unchanging realm of the Ideas, the Universals, the objects of Reason, are the divine. "Plato does not hesitate to use religious language of this knowing. He says that both reason in man and the objects of reason are divine, and speaks of the kinship of one with other." [6] With this conception of the divine, Aristotle is basically in agreement but without the use of the religious language. He says,
"For while thought is held to be the most divine of things observed by us, the question how it must be situated in order to have that character involves difficulties." [7]After discussing these difficulties, he concludes,
"Therefore it must be of itself that divine thought thinksThis self-thinking thought is the divine. Thus both Plato and Aristotle held reason to be divine. God is the divine or eternal realm of the Ideas in Plato's philosophy, or he is a self-thinking thought of Aristotle's philosophy.
(since it is the most excellent of things)
and its thinking is a thinking on thinking." [8]
According to the Greek thinkers, Reason is the divine or God. But since the concepts of God and man are correlatives, the Greek concept of man reflects the image of this god. Since reason is god, man viewed in the light of this god, is a rational animal. Reason is the divine part of man. Aristotle says,
"It would seem, too, this (reason) is the true self of every man,
since it is the supreme and better part.
It will be strange, then, if he should choose not his own life, but some other's...
What is naturally proper to every creature is the highest and pleasantest for him.
And so, to man, this will be the life of Reason,
since Reason is, in the highest sense, a man's self." [9]
This is not the Bibical view of man or of God. God is not Reason. God is a person (or more accurately, three persons) whose existence is not in His reason but in His unlimited sovereign free decision and will; man is also a person (or more accurately, a unity of spirit [person] and body - see Gen. 2:7) whose existence is also to be found, not in his reason, but in his limited free will and decision. And since decisions involve a reference to an ultimate criterion beyond the self, to a god, the Bibical view of man is that he is a religious animal, a being who must have a god. Reason is not the divine part in man but is a function of the will of the person. To be is to choose, not to think or to know. Knowledge and reason depend upon a prior decision as to what is real.
"...whatever evidence one accepts,It is upon decision that any knowledge finally depends. Reason is not the ultimate criterion but the sovereign will of the Creator who made all things and has revealed Himself in Jesus Christ. This basic incompatibility between the Greek and Biblical view of God and man explains the conflict between Greek philosophy and the Christian faith and the failure of the attempted synthesis of these divergent points of view by Augustine and Aquinas. All attempts to synthesize the classical Greek view of God and man with the Biblical view will fail. Worst of all, the Biblical view of God and man will be obscured and misunderstood.
whether that of experience or that of logic,
will depend upon neither logic or experience alone,
but upon a decision by the individual concerned in favor of the one or the other." [10]
The true founder of the Eleatic school is not Xenophanes, but Parmenides of Elea (c. 515 B.C.- c. 450 B.C.). He is probably the most important philosopher before Socrates, being the first to focus on the central problem of metaphysics, the problem of being. He held that "thought and being are the same thing," and that "being is and it is impossible for it not to be; it is impossible that non-being is." That is, being exists and non-being does not exist. Being is ungenerated and indestructible. It cannot come into being out of what does not exist. Neither can it cease to be, since being is not non-being. Hence being is eternal. Change is impossible; for if anything changes, it ceases to be what it is and becomes what it is not; and since being cannot cease to be and non-being does not exist, change is impossible. And also movement is impossible; for if anything moves, it must occupy empty space where it was not; and since empty space is non-being and does not exist, movement is not possible. And there can only be one being; for if there where more than one thing, they would have to be separated by empty space; since empty space is non-being and does not exist, they cannot be separated and thus must occupy the same space; thus the many are one and being is one. Finally being is homogeneous, not having parts; for if it has parts, then it would be many; but since being is one, it has no parts and thus is homogenous. From this Paramenides argued that being is finite, like the surface of a sphere it is "perfected on every side," equally distance from its center at every point. Paramenides' student, Mellisus of Samos (5th cent. B.C.), rejected his teacher's conclusion that being is finite; being must be spatially and temporally infinite. For if being is finite, then beyond it there would be empty space; but since empty space is nothing, non-being, it does not exist and thus being occupies all space. Thus being is spatially infinite. Mellisus, like Parmenides, rejected a void or vacuum, empty space, as impossible and non-existent, "for what is empty is nothing. What is nothing cannot be." Zeno of Elea (c. 490-430 B.C.) was a firm adherent to Parmenides's ideas and tried to show that they are true by showing their opposites are impossible and absurd (reductiones ad absurdum). By this form of argument he attempted to show that pluralism (that reality is many, not one), empty space, time and motion are impossible. These famous arguments are known as Zeno's Paradoxes.
Plotinus was born in Egypt and studied in Alexandria under Ammonius Saccas. After accompanying the emperior Gordian on a campaign in the East, he settled in Rome about 244, opening his own school. He wrote essays for his students about their philosophical discussions. His pupil, Porphyry, collected these and arranged them systematically into six Enneads [groups of nine], that are the major source of Plotinus' philosophy. Porphyry published the Enneads after A.D. 300 with an accompanying Life of Plotinus. Prophyry reports that Plotinus had a mystical experience of union with the divine on four occasions, which union is described in the Enneads and is one of classics of mysticism.
In the fourth and fifth Christian centuries, Neoplatonism provided the philosophical basis for pagan opposition to Christianity. Prophyry in addition to his numerious philosophical treatises, wrote a massive fifteen volume work, now lost, Against the Christians. The Roman emperor, Julian, in addition to decrees against Christians, wrote Against the Galileans, which can be reconstructed from Cyril of Alexandria's refutation of it. In addition to providing the philosophical basis for this opposition, Neoplatonism also provided the philosophical framework for the thought of several Christian theologians: Gregory of Nyssa, Victorius, Ambrose, Augustine, and later Dionysius the Pseudo-Areopagite. The influence of Neoplatonism continued in both the Western and Eastern churches. Even in the twentieth century elements of it has appeared in the thought of Paul Tillich.
"There is a science which investigates Being as Being and theAristotle divides being into two kinds:
attributes which belong to this in virtue of its own nature.
Now this is not the same as any of the so-called special sciences;
for none of these treats universally of Being as Being.
They cut off a part of Being and investigate the attributes of this part."
Aristotle derived this dual classification of being from his teacher, Plato, who held that "true being" was something not subject to change and decay. According to Plato, our world of the senses displays only becoming; everything in it is coming into being and going out of being; nothing really is. Only that which is changeless is real, thought Plato; reality is permanent and immutable. Plato held that these two primary modes of being, permanence and change, are separate and distinct from each other. The permanent is the realm of Ideas or forms, apprehended by the mind only, and the changing is the realm of the sensibles, apprehended by the senses.
Aristotle rejected this dualism of being, but accepted the distinction between the two kinds of being. Aristotle combined these two kinds being in the concept of "substance." He introduces the distinction between "substance" and "accident"; a substance or thing has relatively independent being from other things, whereas accidents or qualities have no independent being, but exist in a substance. Blue and hard are not like houses and rocks. These qualities must "inhere" in a substance; they qualify the substances. Now substances, in some fundamental way, remain the same, although their qualities may change; that is, substances retain their identity through change. A house may be white or red, but even if the color of house changes, the house remains a house; its identity is perserved through the change. Substance, then, represent the relatively permanent side of reality and qualities the changing side. Instead of separating the permanent from the changing, as Plato did, Aristote unites them in things as substances and their accidents or qualities.
But how is change possible, if the permanent is primary, more important, "realer," while change is secondary, less important, less real? Aristotle attempts to solve this problem by introducing the distinct between "form" and "matter," in which he interprets "matter" as potentially and "form" as actuality. According to Aristotle, change is the process of going from potential to actual. The block of stone is potentially a statue and the statue is the actualization of this potential. Matter is potentiality and form is actuality. Aristotle combined form and matter in a series from prime matter to pure form; the form of a lower level is the matter of the higher level. At the top of this hierarchy of form and matter is pure form, pure actuality, pure being, God.
What is the Biblical view of man? What does the Bible say about the nature and origin of man? Let us go back to the early chapters of the book of Genesis and examine what it says about the origin and nature of man in order to begin our investigation and try to answer these questions and to understand the Biblical view of man.
The basic Biblical assertion about man is that he is created by God.
"26 Then God said,Man is a creature. He is not God. He is not divine. He does not have a "spark of the divine" in him. He is a created being, and as such is under the sovereignty and dominion of God by creation. But even though man is a creation of God, he is different from the rest of creation. Genesis 1:26-27 tells us that God created man in His own image. This makes man different from the other creations of God.
'Let us make man in our image, after our likeness;
and let them have dominion over the fish of the sea,
and over the birds of the air, and over the cattle,
and over all the earth,
and over every creeping thing that creeps upon the earth.'
27 So God created man in his own image,
in the image of God he created him;
male and female he created them." (Gen. 1:26-27)
Man was created by God and, in contrast to the rest of creation, was created in the image of God. What is the image of God? The image of God is a person, the Son of God, who is Jesus Christ, the God-man. The Apostle Paul says,
"13 For He [God] delivered us from the domain of darkness,God's Beloved Son is the plan and pattern according to which God created man. As such He is the first-born of all creation. Not that He is the first created being, but that He is the pattern by which all men will be born. God created man with the anticipation that His Son would become man, a human being. Thus He is the first-born of all creation.
and translated us to the kingdom of His beloved Son.
14 in whom we have redemption through His blood,
the forgiveness of sins;
15 And He is the image of the invisible God,
the first-born of all creation."
(Col. 1:13-15 NAS; compare II Cor. 4:4; Rom. 8:29);
"26 Then God said,In this passage of Scripture, we find that there are two aspects to man being created in the image of God. The first aspect is found in the words
'Let us make man in our image, after our likeness;
and let them have dominion over the fish of the sea,
and over the birds of the air, and over the cattle,
and over all the earth,
and over every creeping thing that creeps upon the earth.'
27 So God created man in his own image,
in the image of God he created him;
male and female he created them." (Genesis 1:26-27)
But there is also a second aspect to man being created in the image of God. In these verses of Genesis one, we see this aspect in the words
"So God created man in his own image,This does not mean that God is male and female but that He is more than one person existing in an unique personal relationship or fellowship. As God has created man, he cannot live alone. In Genesis 2:18,
in the image of God he created him:
male and female he created them" (Gen. 1:26).
"The Lord God said, 'It is not good that the man should be alone;Of all the creatures God had created "there was not found a helper fit for him" (Gen. 2:20). So God created, out of man, woman. Man, in the very way in which he was created had a social need -- a need for fellowship. This need could only be satisfied through an equal fellow creature. None of the animals could satisfy this need for fellowship. So God made an equal being, a woman. Man as a social being is able to enjoy a reciprocal personal relationship or fellowship with an equal being. In this respect man is also like God. In God there is an equality and fellowship between the three persons of the Godhead.
I will make him a helper fit for him.'"
Man's dominion over creation and his fellowship with an equal being -- woman -- are two aspects of man being created in the image of God. Both of these presuppose freedom -- freedom of choice and freedom of action. This freedom is the presupposition and the possibility of being in the image of God. Since God created man with freedom, dominion over creation and fellowship with equal beings become possible. With freedom of choice and action man can exercise his dominion over creation. And since love is the essence of fellowship, with his freedom of choice and action, man can love an equal being and thus enter into fellowship with her. This freedom of choice and not his reason, neither self-consciousness, nor self-transcendence, is that which make possible man's dominion over creation and fellowship with an equal being. This is what distinguishes man from the rest of creation. This freedom of decision is what gives to man his existence as a person or self and to his reason that human and personal character. Man is a personal being in a created physical world and as such is a union of spirit (person or self) and body (physiological organism).
"Then the Lord God formed man of the dust from the ground,When God breathed into the nostrils of the body of man the breath of life, He created man's spirit and man became a living soul. The soul of man is the union of this created spirit and the body formed from the dust of the ground. Thus man is diparite being having two parts, spirit and body; the soul is not a part of man but is the union of man's created spirit and his body.
and breathed into his nostrils the breath of life;
and man became a living soul (nepesh)" (Gen. 2:7 KJV).
Thus man, as created by God, is a personal being, a unity of spirit [person] and body (see Gen. 2:7), having dominion over creation and fellowship with another equal human being (woman). Man's existence as a person is also to be found not in his reason but in his limited free will and decision. And since decisions involve a reference to an ultimate criterion in or beyond the self, to a god, the Bibical view of man is that he is a religious animal, a being who must have a god.
The first man Adam and his wife Eve used their freedom to disobey God and choose a false god, wisdom and knowledge; that is, Reason. The basic sin is turning from the true God and to faith in a false god of some kind; it is idolatry. Sin is any choice contrary to ultimate allegiance or faith in the true God. The consequence of Adam's sin was death: physical death (the separation of their spirits from their bodies) and spiritual death (the separation of their spirits from God). In other words, they lost their fellowship with God and with each other and their dominion over creation. But even though they have fallen from the image of God, they still are persons and still have the freedom of choice.
The descendants of Adam are born not in the image of God but in the image of Adam, the man of dust, the old man, and as such are subject to death, physical and spiritual. Death has been inherited by all men. And since they have been born into the world spiritually dead, alienated from God, not knowing the true God, and since they must have a god, an ultimate criterion of decision, they choose a false god and thereby sin. The creation, man himself, contains a knowledge about the true God which leaves them without excuse for the sin of idolatry. But this knowledge is about the true God and is not a personal knowledge of the true God which comes from fellowship with God.
Salvation is the restoration of fellowship and communion with God through the historical death, bodily resurrection and exaltation of Jesus Christ and the coming of the Holy Spirit. God in His love for man has sent His Son into the world to become a man - Jesus Christ. He is the image of God, the perfect man. But He came not just to be what man should have been or to give man a perfect example but to give them life and restore them to the image of God. He did this by entering into their condition of spiritual and physical death on the cross. So that as Christ was raised from the dead, they might be made alive with Him in His resurrection. That is, Christ's death was their death and His resurrection is their resurrection. That is, salvation is basically from death to life. Also, Jesus Christ was exalted to the right hand of God as Lord to become their Lord and their God. God has sent the Holy Spirit to save man from death and sin by revealing Him personally to them in the preaching of the gospel, the good news of what God has done for man in Jesus Christ's death and resurrection, of Jesus Christ as their Savior who died for them and as their resurrected and living Lord. When a man responds to this revelation by turning from his false gods (repentance) and turning to the true God, acknowledging Jesus as his Lord (faith) he is saved from sin. And since in this decision of faith he receives the living Christ as his life and identifies himself with the death and resurrection of Christ, a man is also saved from spiritual death, being made spiritually alive to God in Christ. Thus man is now being restored to the image of God.
But this restoration is not now yet complete. At the second coming of Jesus Christ (Acts 1:9) the believers' bodies will be resurrected if they die before He comes (I Thess. 4:14-17), or will be transformed into bodies like His resurrected body if they are alive at His coming (I Cor. 15:51-52; Phil. 3:20-21; I John 3:2). Thus physical death will be replaced with physical life just as spiritual death was replaced with spiritual life when they first believed. What was begun at conversion will be brought to completion (Phil. 1:6) at Christ's coming. Spiritual life will become eternal life - eternal fellowship with the Father, the Son and Holy Spirit (heaven) (Rev. 21:3). Thus will man be restored to the image of God. And their salvation is from death (both spiritual and physical) unto life, from sin (idolatry - trust in false gods) unto righteousness (trust in the true God), will be completed.

Although Augustine wrote against pagan philosohy, he still showed a strong predilection for Neo-Platonism. There is a depreciation of sense-objects in comparison with eternal and immaterial realities; a grudging admission of practical knowledge as a necessity of life; the insistence on "theoretic" contemplation and purification of the soul and liberation from the slavery of the senses. Philosophically this predilection is shown in the Platonic and Neo-Platonic view that the objects of the senses, corporeal things, are inferior to the human intellect, which judges them with reference to objective standard as falling short. These standards are the immutable and eternal universal ideas or forms. The standards of goodness and beauty, for example, correspond to Plato's first principles or archai, the exemplary ideas, and the ideal geometrical figures correspond to Plato's mathematical objects, ta mathematika, the objects of the dianoia.
To the question, which was asked of the Platonic Ideas, "Where are these ideas?" Augustine answers that they are in the mind, the Nous, of God, they are the thoughts of God. The Neo-Platonics made this suggestion and Augustine apparently accepted it as the answer to the question: Where are they? Augustine does not accept the emanation theory of Neo-Platonism, where the Nous emanates from the One as the first hypostasis. But the exemplar ideas and eternal, immutable truths are in God. This theory must be accepted, Augustine argues, if one wishes to avoid having to say that God created the world unintelligently. Thus creation is like Plato's formation of the sense-world by the divine artisan, the demiurge, except that there is no pre-existent matter; God created it out of nothing.
Thus the world of creatures reflect and manifests God, even if it does in a very inadequate way. The order and unity of creatures, their positive reality, reveals the goodness of God and the order and stability of the universe manifest the wisdom of God. But God, as the self-existent, eternal and immutable Being, is infinite and, as infinite, is incomprehensible. God is His own Perfection and is "simple," without parts, so that His wisdom and knowledge, His goodness and power, are His own essence, which is without accidents. God, therefore, transcends space in virtue of His spiritually and simplicity, as He transends time in virtue of His eternity. "...He is above all things. So too He is in no interval nor extension in time, but in His immutable eternity is older than all things because He is before all things and younger than all things because He is after all things." From all eternity God knew all things which He was to make. He does not know them because He has made them, but rather the other way around. God first knew the things of creation though they came into being in time. The species of created things have their ideas or rationes seminales in the things themselves and also in the Divine Mind as rationes aeternae. God from all eternity saw in Himself, as possible reflections of Himself, the things which He could create and would create. He knew them before creation as they are in Him, as Exemplar, but He made them as they exist, that is, as external and finite reflections of His divine essence. Since God did nothing without knowledge, He foresaw all that He would make, but His knowledge is not distinct acts of knowledge, but "one eternal, immutable and ineffable vision." In virtue of this eternal act of knowledge, of vision, to which nothing is past or future, that God sees, "foresees," even the free acts of men, knowing them "beforehand." This exemplarist doctrine passed into the Middle Ages and was taken as characteristic of Augustinianism.
Averroism was that form of Aristotelian philosophy based on the
commentaries of Aristotle written by the Arabic philosopher Averroes
(Mohammed ibn Roshd) (1126-1198), whose Latin name was a corruption of Ibn
Roshd. His commentaries became known to Western scholars in their translations
by Michael Scottus, Hermannus Alemannus, and others at the beginning of the
13th century. Albertus Magnus relied heavily on Averroes' commentaries on
Aristotle, while noting certain difficulties.
The teachings of Averroes became the basis for a whole school of philosophers,
represented first by the Faculty of Arts at the University of Paris, among
whom the most prominent was Siger of Brabant. No philosophy was more often
condemned in the Middle Ages by church leaders and councils than Averroism.
It was condemned in 1209, 1215, 1240, 1270, and 1277. It was condemned for
its teachings that held that
(1) matter is eternal (God and the world are co-eternal),
(2) the absence of personal immortality (the numerical identity of the
intellect of all men), and
(3) the doctrine of double truth (that a proposition
may be true in philosophy and false in theology).
Aquinas, relying on the translation of Aristotle by William of Moerbecke, criticized Averroes' interpretation of Aristotle.
From 1272 Aquinas taught at the University of Naples. He died on March 7, 1274 on the way to the Council of Lyons. Aquinas was canonized in 1326, made a Doctor of the Church in 1567, and Pope Leo XIII (Aetrni Patris) gave his philosophy official status in 1879.
At the heart of Aquinas' philosophy is his concept of being. And to understand being reason must use the principle of analogy to fix the appropriate meaning of the term. And since there are certain "transcendental" terms that go beyond any genus, and apply to everything that is, they are attributes of everything. These transcendentals are ens (being), res (thing), unum (unity), aliquid (distinction), verum (true), bonum (good). All beings (ens) are things (res) with unity (unum), distinguished (aliquid) from what is not themselves. And since all beings are what they are, in relation to knowledge, they are true (verum). And since all beings tend toward their ends or goals, they are good (bonum). When the principle of analogy is applied to these transcendentals, human reason can begin to understand, within limits, the nature of God. The kind of analogy to be used here is the analogy of proportionality; that is,
The properties of x The properties of y are to as are to x's being y's beingBy the use of this analogy of proportionality, human reason can begin to understand how God's being exceeds any other being by comparing the properties of being. Since there are five properties of being, there are five ways to establish this comparison. From this comparison there arises the idea of a perfect being, God. God is perfect and unchanging being, utterly simple (without parts) and unitary, hence indestructible, absolute truth and goodness, not related to the world, yet everything in the world related to Him. Since the divine mind contains the archetypes of all things, simply in knowing Himself God is able to know at once all that is, was, or will be. In His self-knowledge all time is concentrated in an eternal moment, in a totum simul. Aquinas argued that while God is the primary cause of all things, there are secondary causes and among these secondary causes some are necessary and others are contingent. Thus free will is compatible with God's foreknowledge and God's causation of all things.
At the heart of Aquinas' ontology is the real distinction between essence and existence in all finite beings. Aristotle distinguished between actuality and potentiality, but he applied this to form and matter, not to the order of being. Aquinas argued that only God is pure being, pure actuality (actus purus), with no potentiality whatsoever. That is, God's being is from Himself, not from another. He has aseitas in contrast to those beings that have derived their being from another. Thus God is necessary being, because God's essence (what He is) and existence (that He is) are identical, hence He cannot fail to exist. In finite creatures, their essence (what they are) is separate from their existence (that they are). Aristotle does not make or use this distinction between essence and existence; Aquinas introduced this distinction because it allowed him to explain the difference between God and the angels. Angels are pure forms like God, but their essence and existence are not identical, unlike God whose essence and existence are identical. According to Exodus 3:14 God revealed Himself as the "I am". Aquinas interpreted this to mean that God alone is Being (I-Am-ness). Everything else has being. God's essence is identical to His existence; that is, it is of His essence that He exists. Thus God is a necessary being, not a contingent being like everything else; He cannot not exist. Neither can God change, since He is without potentiality to be anything other than he is. Likewise, God is eternal, timeless, since time implies a change from a before to an after. But as the I-am, God has no before and no after. God is also simple (indivisible), since He has not potential for division. And he is infinite, since pure act as such is unlimited, having no potentiality. Thus God is perfect Being.
Aquinas views reality as a hierarchical pyramid of being. Like Aristotle, he viewed the lowest level of reality as pure matter, without form, that is, prime matter, and the highest level as pure form, without matter, that is, God. God is regarded as pure actuality, Prime matter, on the other hand, is viewed as pure potentiality. But Aquinas also held that since prime matter cannot exist by itself, it is dependent upon form for its existence in a concrete individual substance. Since form, on the other hand, is not dependent upon anything for it to exist, it can exist from itself and indeed as pure form it must exist. But in Aquinas' view, prime matter does not exist; it has only the potentiality of existence. God, on the hand, does exist and cannot avoid existing. Like Aristotle, Aquinas held that between these extremes there are to be found various levels of formed matter, the order of nature. Concrete individual substances are constituted of the abstract metaphysical elements of form and matter. Aristotle described substance as the union of form and matter. For example, man is the substantial union of form (mind or intellect) and matter (body).
By contrast the Augustinians of the thirteenth century held that man is the union of two different substances, the intellectual soul and the material body; a man is a soul in a body. That is, there is gap between the intellectual soul and the material body, which for Bonaventure is the guarantee of the soul's spirituality and its immortality. Albert the Great somewhat closed the gap by asserting that there is one substantial form between the soul and the body, the form of corporeity. The soul, he tells us, can be viewed either in itself, as an intellectual substance, or as a form exercising the function of animating a body. The first view, defining the soul's very nature, he attributes to Plato; the second, describing one of its external and accidental functions, he attributes to Aristotle. Here Albert was simply following the Arabic philosopher Avicenna (980-1037), who had already tried to reconcile the two Greek philosophers in this way. What neither Avicenna nor Albert could see by considering the soul as a substance in another substance such as the body, was the relation between them is purely extrinsic and accidental. Now this view did safeguard the independence of the soul from matter and its immortality; but it is difficult to see how, under these circumstances, man is anything more than an accidental aggregate of soul and body. Thomas Aquinas saw this problem. The view of the Aristotelians and Averroism, on the one hand, threatened the independence of the soul from the body and the immortality of the soul; but, on the other hand, the view of the Augustinians and the Avicennians threatened the unity of man.
Albert the Great considered soul and body as radically distinct because he thought of each as an essence which by definition differs from each other. The Avicennian world is composed of essences of this sort, each of which corresponds to a definition and includes only what is contained in its definition. Whatever is outside the definition is accidental to it. For example, when we define man as a rational animal, nothing is said about his individuality and universality; these are accidental to the essence of man as such, so that it can be individual in Peter and Paul and universal in the concept we form of it in our mind. In addition, although the definition of a thing tells us what it is, it does not say whether it exists or does not exist. That is, existence itself is not included in the essence of a thing but is accidental to it. This is true of everything except God, whose essence includes his existence. William of Auvergne (1180-1249) adopted from Avicenna this view of the accidentality of existence and used it to explain the contingency of created being. For, he reasoned, if essence of God is existence, all other things must receive existence as an accident of their essence. Existence, then, is given them as a gift and they are contingent in their very being. Albert the Great expressed this same view, but Aquinas transformed and used it for his own purposes.
Thomas Aquinas saw that solution to the problem of the unity of man was, not to consider essence as primary in the understanding of being, but existence. Instead of the world being composed of forms or essences, Aquinas viewed the world as consisting of individual acts of existing (esse). Existence has the primacy in the concept of being. The form of each being is that whereby it is what it is; it is the principle that specifies and determines it to be a certain kind of being. But in addition to form there is a further and ultimate act[uality] that makes it to be or to exist. This is the act of existing, which Thomas describes as "the actuality of all acts" and the "perfection of all perfections". It is the most profound in any being, its ontological nucleus, so to speak, the source of all its perfections and its intelligibilities.
The soul when looked at from the point of view of essence or nature, it appears deficient and in need of the body, for it is only a part of the complete essence of man. But from the point of view of existence, this is not true. As a substantial form the human soul has a complete act of existing (esse), and since it is a spiritual form, its act of existing is itself spiritual. When it informs the body it communicates to it that act of existing so that there is but one substantial existence of the whole composite. For Thomas, therefore, the unity of man does not consist in a combination or assemblage of various parts or substances, but in his act of existing. This is the reason that Aquinas denied the presence of several substantial forms in man. If a substantial form gives substantial existence, several forms of this kind would give man several existences and his unity as a substance would be destroyed.
Aquinas upheld this doctrine of being in the face of wide spread opposition from his contemporaries. On the one hand, philosophers like Siger of Brabant wished to return to the Aristotelianism of the Averroes. Siger reminded Thomas that Aristotle had written about form and matter and composition of the two in substances; he had never mentioned an esse distinct from them. On the other hand, he faced the opposition of those who admitted esse as a distinct principle of being but simply treated as an accident of essence. This had been the view of William of Auvergne and Albert the Great, who traced the concept to Avicenna. For Thomas this was still to view being as primarily essence or form and to reduce the role of existence to an accidental determination of essence. Thomas stood alone in his century and indeed in the whole Middle Ages for the doctrine of existential being.
