The terms "actuality" and "potentiality." Possible potentials precede existent actuals, what changes a potentiality into an actuality, why a potentiality cannot be an actuality and cannot be the cause of change. Thus, actualities must precede even possible potentialities, must be eternal and are the real cause of change. 4:52 Three ancient philosophers who asserted the eternity of actuals 5:24 Aristotle's proof that there are things (actuals) that have always existed. 6:00 Only actuals (things in actual motion) have the potential to change. Potentials cannot cause actuals. 6:42 An example with eating an apple to illustrate the difference between actuals and potentials. Thought as an actual movement. Movement without being moved. 9:52 What Aristotle thought about Plato's the Good. How knowledge of the Good is useful. 11:46 How the Unmoved Mover causes movement and the identity of the Unmoved Mover. 15:06 The nature of God (life and eternal existence) and what God enjoys--happiness of thought. 16:32 Qualities of the Unmoved Mover. 18:13 Another proof from Aristotle's of God 19:13 Aristotle's view of the soul. Three kinds of nested souls: Plants, animals and humans. The mind, when free of thoughts, is immaterial and eternal. 22:05 Aristotle's four causes of change: material, formal, efficient and final. 23:29 Aristotle's substantial form (the essence of something, in Greek "ousia"). The efficient cause of a substantial form of an animal is its parents. 25:34 The importance and gift of Greek thought. 26:16 Another world-wide synchronicity during the time of Classical Greek thought.
