4. Looking at geometry, we are told that a right-angle triangle has angles totaling 180° and that one <strong>of</strong> itsangles is 90°. No material rectilinear triangle, however, is perfect, but the relationship a 2 + b 2 = c 2 isperfect and eternal.5. There is a wonderful correspondence between the realm <strong>of</strong> matter and that <strong>of</strong> abstraction. Oftenmathematical abstractions predate physical discoveries which, however, they describe exactly. Ourwonder at this, and our sense that it is no coincidence, are Pythagorean.E. If we take the creative force behind all existing things to be a divine force, then we can only conclude thatnumber is a kind <strong>of</strong> divinity, that number, in its abstract, transcendental nature, is divine.F. Consider, however, numbers that do not match up with anything material, such as π or − 1 . Nonetheless,π is needed to calculate the circumference <strong>of</strong> a circle.1. For the Pythagoreans, coincidence cannot explain this. Further, the odds are long that a mathematicianwould come up with a complex equation that, 200 or 300 years later, would perfectly explain somebrute physical fact.2. Such occurrences, then, must express some plan. The ultimate plan must be abstract but capable <strong>of</strong>generating the physical reality. The abstract plan must also be a plan <strong>of</strong> relationships.III. What kind <strong>of</strong> governor was Pythagoras? The answer is: “not successful.”A. The people <strong>of</strong> Crotona ultimately staged riots in reaction to Pythagoras’s “old-time religion.”B. How could Pythagoras be a man <strong>of</strong> affairs at all? Is politics the sort <strong>of</strong> activity in which a philosopherengages?1. As Aristotle teaches, we seek precision only ins<strong>of</strong>ar as the subject allows it. There could be noPythagorean theorem for political life.2. A philosophically guided state is unlikely to survive the reality in which it finds itself.C. What can we say about Pythagoras as “first philosopher,” a title that he arrogated to himself?1. The word philosophy means “love <strong>of</strong> wisdom.”2. The Greeks had several words for intelligence or knowledge, some denoting scientific knowledge andsome, practical knowledge.3. Sophia, however, was what the wise person possessed, the person who delves into core questionsabout the meaning <strong>of</strong> life.4. Pythagoras appropriately called himself a philosopher because he devoted himself to an inquiryserving the purposes <strong>of</strong> knowledge. He sought to discover what it is that makes anything possible andreal and, as in chemistry and particle physics today, found the answer in number.Recommended Reading:Fideler, D. ed. The Pythagorean Sourcebook and Library. Phanes Press, 1987.Questions to Consider:1. Summarize in what ways Pythagorean “numerology” is like and unlike modern mathematical models <strong>of</strong> reality.2. Explain the striking agreement found between abstract mathematics and actually occurring natural items.8©2004 The Teaching Company Limited Partnership
