The Great Philosophers

1. 

   E1. Plato

   Sep 6, 1987 · 43m

   The dialogues of Plato are analyzed in this program by Cambridge philosophy professor Miles Burnyeat. Seeing Plato's ideas initially as extensions of those of his teacher, Socrates, Burnyeat explains the development and content of Plato's original; doctrines of knowledge as virtue, the immortality and tripartite division of the soul, and the theory of forms (ideas). Plato's political philosophy is discussed within the context of the notion of the ideal state—a political utopia ruled by philosopher kings.

   E2. Aristotle

   Sep 13, 1987 · 43m

   In this program, the far-reaching philosophical ideas of Plato's star pupil are examined by noted Brown University professor Martha Nussbaum. Aristotle overcomes Plato's dualism of the intelligible and sensible worlds with his principle of inseparable nature of eternal matter and form. The principles of potentiality and actuality are examined, along with Aristotle's theory of the four causes—material, formal, efficient, and final—which account for changes in all things. These theories of constancy and change are credited with the progress of scientific inquiry over the ages.

   E3. Medieval Philosophy

   Sep 20, 1987 · 43m

   This program examines the ideas of the medieval philosophic theologians, particularly St. Thomas Aquinas. Oxford medieval philosopher Anthony Kenny discusses Aristotelian logic as the basis of Aquinas' thought, and disputes charges that medieval philosophy merely reinforced extant Christian views. Logical methods employed by Aquinas are discussed as precursors of the scientific methodology of later philosophers, such as Descartes.

   E4. Descartes

   Oct 4, 1987 · 43m

   I think, therefore I am. Rationalist philosopher and mathematician René Decartes, considered the father of modern philosophy, held this as self-evidently true. In this program, Bernard Williams of Kings College examines Decartes' theory of knowledge and his use of skeptical inquiry to affirm reality, including the existence of God. Descartes' theory of physical and mental substances, and Cartesian dualism—which allows the concept of science to coexist with the notion of God—are examined.

   E5. Spinoza and Leibniz

   Oct 11, 1987 · 43m

   The ideas of rationalist philosophers Baruch Spinoza and Gottfried Leibniz are examined in this program by philosophy Anthony Quinton. Spinoza favors a pantheistic God who has matter and mind as two attributes, and who is the ultimate substance and explanation of the world. Leibniz sees the real world as consisting of an infinity of things purely spiritual, where everything, including space, is a phenomenon—a by-product of areal world with an infinite array of spiritual centers. Both philosophers construct a world that is very different form what the average person perceives, and both reject Cartesian duality.

   E6. Locke and Berkeley

   Oct 18, 1987 · 43m

   This program examines the philosophies of British empiricists John Locke and George Berkeley. Philosopher Michael Ayers of Oxford interprets Locke's skeptical theory that all knowledge is sensory and speculative, and that the true nature of the world can never be known as an attack on Descartes' theory of innate ideas. Conversely, Berkeley insists that we cannot have sensory knowledge of material substances because the exist only in the mind. Even the laws of nature, Berkeley says are merely the regularities of our own perceptions or ideas.
