Notes on Ancient and Medieval Philosophers
by Ryan P. Snuffer --Maimonides Why Study Philosophy? Whether a person realizes it or not, his or her thinking has been influenced by philosophers who lived hundreds or thousands of years ago. Men such as Plato, Aristotle, and Thomas Aquinas are still having a profound impact on modern philosophy and theology. One can better understand the present trends in academic circles if the past is better understood. This syllabus is largely a compilation of class notes and class lectures by Norman Geisler.[1] Throughout world history, various philosophical worldviews have dominated at different times. From 600 B.C. to A.D. 400 the religious emphasis was on polytheism (many gods) and henotheism (a super-god like Zeus). From A.D. 500 to 1500, theism was the dominant religious worldview. Agnosticism was dominant between 1500 and 1900. Atheism has been the dominant view since 1900. This is evident in the teachings of Darwinian evolution and secular humanism that have dominated education and other areas of public life. Of course it would be oversimplification to suggest that there were not groups of people within each of these time periods that were exceptions to the dominant view in intellectual circles. This syllabus is not exhaustive. This is really a list of ancient and medieval philosophers of western culture. The section on ancient philosophy looks at more than two dozen philosophers who helped to lay the groundwork for much of western thought that was to follow. The Pre-Socratic philosophers were polytheistic. They had a difficult time reconciling their first principle with their view of God. The section on medieval philosophy only looks at a handful of the most important western philosophers, though these men are examined in more detail than their ancient predecessors. Many of the questions unanswered by the ancient philosophers were answered, due largely to the influence of Christianity. I.
Ancient Philosophy (Pre-Socratic [600 B.C.] through
Plotinus [A.D. 250] ) Several important philosophers preceded the “big three” that have been household names for more than 2400 years. Few have heard of their names. Fewer still know anything they taught or wrote. Yet, these individuals set the stage for the teachings of Socrates, Plato, and Aristotle. The first of these is Thales.

According to Herodotus, he accurately predicted a solar eclipse in 585 B.C. b. He constructed an almanac. c. He introduced the Phoenician practice of guiding a ship’s course by the constellation Little Bear. 4. Epistemology a. He asked, “What is the ultimate nature of the world?” b. He believed that the Earth was a flat disk that floated on water. 5. Metaphysics a. He believed the primary element was water, and that all things were various forms of that one element.[2] b. He was polytheistic. c. He was the first to conceive of the idea of unity in diversity.

It is temporally infinite, having neither beg9nning nor end.” b. Argument for monism: 1) “There is only one thing in the universe, because if there were many they would have to differ. 2) There are only two ways to differ, either by being or non-being (nothing). 3) Things cannot differ by non-being because to differ by nothing is to not differ at all. 4) Things cannot differ by being because being is that which they have in common (makes them identical). 5) Therefore there are no differences and no two beings; there is only one being in the universe, hence, monism.” c.

a 2. Epistemology—All humans have certain “primary conceptions” and “moral intuitions” on which they can build. 3. Metaphysics—“All events should be viewed as God’s gifts.” 4. Ethics—Man is basically good. Education can help to produce “unerring moral judgment.” AA.Justin Martyr 1. He was born a pagan, and later became a Christian
after studying Greek philosophy. He was martyred in 2. He was a Christian rationalist. He considered philosophy to be at the very heart of Christianity and related to the Logos. 3.

We wonder because we believe, not believe because we wonder. 4. Once a person believes, he should use reason to examine the grounds of his faith. 5. Those truths which are arrived at by human reason are corrupted by philosophy.
Clement of DD.Plotinus 1. He lived A.D. 205 to 270. 2. He was a neo-Platonist; he revived Platonic dualism. 3. He wrote the Enneads. 4. Metaphysics
Here is a brief description of each:
Further explanation:
a. Medieval Christianity—Proclus-mysticism and asceticism b. Religious language–the via negativa-knowing God by negation c. Spinoza–the father of modern rationalism and pantheism, and anti-supernaturalism. The view held by Einstein. He is the fountain head of higher criticism of the Bible. d. Immanuel Kant—agnosticism. e. Hegel—emanationalism. f. Existentialism—God is reached by a leap of faith. g. Wittgenstein—acognosticism: non-cognitive God-talk. The real truth of God is beyond words. This also leads to existentialism. The Bible just tells us how we should think about God, not precisely the nature of God. h. Whitehead—processism-God is progressively growing i. John Dewey—meliorism-the world is getting better II. Medieval Philosophers It is difficult to underestimate the influence
that these philosophers had on the world of their day, and indirectly, the modern world.
With the light of the New Testament as a guide, these philosophers were able to reconcile the problems of the Greeks
and come up with a philosophy that consistently viewed ultimate reality with God. The first of these men is A. 1. He lived from A.D. 354 to 430. 2. Augustine’s Proofs for God: 3. Cosmological Argument (Confessions 11, 4) a. The universe changes. b. Whatever changes has a cause. c. Therefore, the universe has a cause. 4. Argument from changing forms (On Free Will, 16, 44) a. There are changing forms in this world. b. All change is measured by what is changeless. c. Hence, there is a changeless Form beyond this world. 5. Epistemology a. “Disjunctives—world is either one or many, finite or infinite, temporal or eternal.” b. “The senses give a trustworthy report of what they perceive.” c. Three things we know for sure are: “we exist, we think, we love our existence.” d. Interiorism—“Truth dwells in the inward man.” 1) independent truths cannot be caused by changing and dependent sensations (external stimuli). 2) “Truth cannot be caused by the individual mind” which is ruled by truth. “Truth is public to all minds.” 3) Since truth transcends the individual and is immutable, “it must be caused by an immutable Mind (God).” 6. Metaphysics a. Augustine taught that God was immaterial, self-existent, simple, immutable, and eternal. b. Augustine taught that evil is a privation of good. God is absolutely good, and only created good things. Free will is a good thing. Free will is the source of evil. Nothing that exists is totally evil (totally privated). 7. Influence of Augustine: a. Positive: He was the dominant influence on basic orthodox Christianity and on Christian philosophy of history. b. Negative: Major influence on baptismal regeneration, inspiration of the Apocrypha, Amillennialism, and celibacy. He also influenced late Christian monasticism, anthropological dualism, later rationalism (innate ideas). c. He influenced Anselm and Aquinas theologically. B.
Maimonides-“Moses” 1. He lived A.D.
1135 to 1204. He was born in 2. He was the most influential figure in Medieval Jewish philosophy. 3. His world-view was Aristotelian. He was a religious rationalist. 4. His major contribution was the Mishneh Torah, a code of Jewish law. 5. His philosophical writings influenced the non-Jewish world. His contemporary, Thomas Aquinas, sometimes quoted him. So do many western and Muslim thinkers of today.[5] C. Thomas Aquinas 1. He lived around A.D. 1200. He is considered by many as the greatest systematic theologian of all times. 2. He was influenced greatly by Aristotelian logic. 3. He is often misunderstood by evangelicals. Contrary to the opinion of some, his teachings did not give rise to modern humanism; Francis Schaeffer is wrong about Thomas Aquinas. 4. Thomistic View of First Principles a. All knowledge is based on first principles (otherwise there would be no basis for knowing). b. All first principles are self-evident (true in themselves without reference to anything else). c. There are five basic first principles of knowledge. 1) Principle of non-contradiction (B is not non-B). 2) Principle of identity (B is B). 3) Principle of excluded middle (either B or non-B) 4) Principle of causality (non-B can’t cause B) 5) Principle of finality (Being acts for and end B) 5. Faith and Reason · Aquinas was a strong Calvinist. He taught that people believe in God because He is cause. Reason is never the basis for faith. Authority is the basis of faith. Reason can be used in support of evidence. One should use reason to demonstrate the probability of faith. · Reason that God exists, never reason to believe in God. Belief “that” is different than belief “in.” Belief “that” always precedes belief “in.” · Marriage illustration: One can believe that a person exists and will make a good mate. However, marriage does not become a reality until the commitment is made at the altar. · Presuppositionalists are right when they say one cannot reason a person into believing in God. Thomism teaches “look before you leap.” Presuppositionalism teaches “leap before you look.” · There is a difference between perceiving something and receiving something. You can prove something to someone and still not persuade them to believe. 6. Epistemology · The predicate is reduced from the subject, not deduced from the subject with a first principle according to Aquinas. Once you understand the predicate and the subject, you will “see” it as a self-evident truth. Something is self-evident if it reducible to a first principle. “Every contingent being is caused.” This statement is not self-evident at first, but after some analysis, it becomes apparent. · The central premise of Thomism is: “The act in the order in which it is act is unlimited and unique
unless it is co-joined with passive potency.” · Angels are simple beings like God. Angels are also actualized. They cannot be saved after their rebellion, because they cannot change. The only change they can have is accidental (growing in size or mental capacity) or substantial (to come into or cease to exist). · God is pure “I am-ness.” Aquinas believed that he was pure Augustinian. It is of God’s essence to exist. He is pure being. What can you give to the being that has everything? He cannot change. He needs nothing. All we can give Him is worship. · In heaven, we will have all the knowledge that is possible for us to have. What we strive for on earth we will find rest in heaven. Great athletes can make something difficult look easy. There will be no effort left in heaven. This is Aquinas’ view. · Aquinas taught the analogy concept of God. You cannot give what you do not have. You cannot produce what you do not have. Creation is similar to God in its actuality. Creation is different than God in its potency. Creation must be different because God is infinite and creation is finite. 7. Metaphysics of Aquinas · He gave the only satisfactory answer to Parmenides 1. Parmenides wrongly assumes that being is univocal. 2. Being is analogous (similar) because it is composed of existence (act) and essence (potency). So there are different kinds of being. a. God is being pure and simple and simple. b. All other beings are composed of act/potency. 1). God alone is pure Act. 2). Angels are actualized potentialities with no change in being. 3). Humans are progressive actualized potentialities that are changing · Parmenides’ argument works when one tries to compare two infinite beings. If they are identical in every way, then they are one. However, two finite beings that are identical in every way, except that they have different atoms, are still two separate beings. God is infinite. He is pure Act, without Form or Matter.[6] · Aquinas taught the Cosmological and Teleological arguments. · God cannot create another God just like Himself. God is eternal, uncaused, uncreated, and necessary. It is a logical contradiction to suppose that God could create another Necessary Being. Every creature is dependent or contingent. The moment you come to be, you have the possibility to cease to be. By Him all things consist. Aquinas’ Cosmological argument is vertical (how the universe is being supported/ held together right now). Pure act needs no cause. Only God is pure act. He did not deal with the Kalam argument (cause/effect). · “Why is there something rather than nothing at all?” is one of the greatest of all philosophical questions. · Creation—God did no create the world out of Himself (ex deo). He is not made up of parts, therefore, He cannot take part of Himself and create. He is simple. He could not take his whole self and create a universe or else it would be identical to himself. Neither did he create with pre-existing materials (ex materia). He created ex nihilo. · Aquinas incorrectly denied the Kalam argument and thought that there could have been an infinite number of moments (in theory). Yet he agreed with the Bible that in practice, it did not occur that way according to Genesis. Matter, space, and time were created together. Matter was not created in time. Only God and eternity was ontologically prior to the moment of creation? Nothing was chronologically prior to creation. · The universe is dependent on God for its existence. God is the sustaining cause of the universe. This is the contingency argument of the cosmological argument (vertical). The horizontal argument is the Kalam argument which is related to the originating cause of the universe. · The soul and body are inter-penetrating. There is an overlap. They are not divisible in to two distinct parts. Some, like Louis Sperry Chaffer believe that only the soul bears the image of God. Others believe in monism, like the Adventists, the Jehovah’s Witness, F.F. Bruce. With monism, God must recreate at the resurrection. The old body will remain in the grave. This is anthropological heresy. · Aquinas taught a unity view of man. He also believed that right after conception, that God created a new soul. Augustine held to a Traducian view. Geisler believes the creationist view of Aquinas is problematic because of the sin nature problem. 8. Miscellaneous Facts about Aquinas · Aquinas’ world was dominated by a pantheistic view of God (neo-platonism) · He referred to Aristotle as “the philosopher” and Ambrose as “the commentator.” · Everyone wrote on the commentary of Peter Lombard for their thesis projects in the 13th century. · Aquinas wrote before the teaching of the infallibility of the Pope and the veneration of Mary, etc. · Aquinas was a Calvinist. He wrote that a person can only have faith because God gives them their faith. He also wrote that a person can only be saved by faith, not by works. · Before Vatican II, Catholics greatly respected and studied Aquinas. After Vatican II, they dumped him for a phenomenological approach promoted by the pope. · Aquinas followed Augustine—basis for faith is on God’s authority. The arguments are not the reason for faith, but they support your faith. · He believed that man was depraved and that human reason alone was not enough to convince a person of their need for salvation. God’s existence is provable by using reason. However, this is not the same as believing in God. It is mysterious to say that Christ has two natures, but not contradictory. Sometimes faith goes beyond reason, but never against it. · Four Laws: Eternal Law—the mind of God Natural law—rational creatures participating in eternal law Human law—particular application of natural law to local communities Divine Law—the revelation of God’s mind to humans through revelation

All words or descriptions about God must be univocal, equivocal, or analogical: 1. Univocal—entirely the same 2. Equivocal—entirely different 3. Analogical—similar B. Ontology--Being is one of the three above. Only one of these three views can be correct. 1. If every being in the universe is entirely the same (univocal), then there is only one being—monism. This was the view of Parmenides and was refuted by Aquinas. 2. If being is totally different than non-being . . . or if every being is entirely different (equivocal), then there is only one being also (monism) 3. The only other possibility is for there to be similar beings—an analogy of beings. Either analogy or monism is true. C. Epistemology
D. Kinds of analogy:
Conclusion God is like the world in that He is the intrinsic, efficient cause. He is unlike the world in that He is not the instrumental or extrinsic cause of the world. Do mosquitoes resemble malaria? No. The malaria parasites contain the DNA identical to malaria. Mosquitoes are the extrinsic cause. (See 4 causes in Aristotle). A hammer breaking the mirror—the hammer is the instrumental cause. The person hitting the mirror produces the motion; he also has the thought in his mind to break the mirror—two similarities. Everything that could not be must be ultimately dependent on something that could not not be (a necessary being). This must be an indivisible (simple) being. One cannot tear something apart that has no parts. God has no boundaries. God is Being. God is knowledge. Everything else has knowledge. God is good. Things have goodness. God is love. Creatures have love. The theistic God must true. Humans are changing beings. They come to be and change through time. One could not change if one did not have the potential to change. A person could be something else; a person can become something else. No potentiality can actualize itself. Therefore, there must be a pure actuality. Infinite regression is impossible. As pure Act, God is the First Cause. Why does something exist that could not be rather than nothing at all? This question is adequately answered by the Christian philosophers. The Greek philosophers fell short in this account. It can be said that the Greeks gave the world a valuable foundation on which to build knowledge. There heresies should be dismissed, but should not overshadow their contributions. The Christian philosophers were able to reconcile their Ultimate Reality with their view of God.

Credit must be given to Norman Geisler for many of the statements and the overall organization of this project. Statements in quotations marks without a separate footnote are taken directly from Norman Geisler, Notes on the History of Philosophy: Ancient and Medieval, 1994. [2] This is an interesting idea given the fact that modern science has concluded that all matter is reducible to atoms. The simplest atom is Hydrogen with only one proton and neutron. All other atoms are variations of proton, neutrons, and electrons. [3] Norman L. Geisler, “Faith and Philosophy in Early Church Fathers,” Notes on the History of Philosophy: Ancient and Medieval, 1994. Originally Clement, Exhortation to the Heathen, VI. [4] Ibid.

Though God is without material form, imagine that He is material. If God were infinite materially, He would be made up of an infinite number of atoms. There could only be one infinite material being since the one would use up every available atom in the universe. Whatever it is that makes up the essence of God, if He is infinite, there can only exist One |
