“If there’s no such thing as a mind capable of observing evidence and reasoning according to the laws of logic, then every man’s conclusions express nothing but blind mechanistic reactions. Each man is then a machine — he’s a physical puppet guided by the laws of motion. […] He’s a little billiard ball system, in effect, rattling and quivering by mechanistic necessity.”
— Leonard Peikoff, “History of Philosophy” course, ARI, Lesson 6.
(Materialism implies determinism, which, in turn, denies the mind. I wonder how a mind could have had the idea of denying itself. Original source of the image: Min Then.)
The Pythagoreans attempted to solve the problem raised by Heraclitus and Parmenides by postulating two worlds: one in constant ﬂux, this world; and one eternal and immutable, the world of number. The Atomists attempted a very different reconciliation. In the process, they made possible the birth of modern science. They also caused the destruction of the mind.
“A great many children live in that kind of world thanks to the wanton irrationality of their parents, whose behavior is characterized by constant switching and swimming so that nothing ever holds true from one moment to the next, and by constant contradictions. That is the perfect recipe for the Heraclitean world.”
— Leonard Peikoff, “History of Philosophy” course, ARI, Lesson 3.
(Since very early in the history of philosophy, Heraclitus disregarded the senses as invalid and accepted contradiction in reality. Two and a half thousands years later, we still see the effects of such errors.)
Thales gave rise to philosophy by relying on sensory experience and reason. The next philosopher in line — Heraclitus — not only trailed a different path, but ignited a chain-reaction that ran through history toppling like dominos all that man tried to erect with his reason. It all began with the problem of change and multiplicity; it all ended with my thirteen-year-old niece asking petulantly: “Why can’t I simply decide I am a boy?”
