“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.
