| | Western natural philosophy began with eminent [[Ancient Greece|Greek]] pre-Socratic philosophers such as [[Thales]], [[Anaximander]], possibly [[Pythagoras]], [[Heraclitus]], [[Anaxagoras]], [[Empedocles]] and [[Philolaus]], many of whom were involved in various schools. For example, Anaximander and Thales belonged to the Milesian school. [[Plato]], briefly and [[Aristotle]] at length, in works that survived to today, continued these studies of nature. | | Western natural philosophy began with eminent [[Ancient Greece|Greek]] pre-Socratic philosophers such as [[Thales]], [[Anaximander]], possibly [[Pythagoras]], [[Heraclitus]], [[Anaxagoras]], [[Empedocles]] and [[Philolaus]], many of whom were involved in various schools.

| | + | |
| | + | Natural philosophy presupposes that change is a reality. Although this may seem obvious, there have been some philosophers who have denied the concept of change, such as Plato's predecessor [[Parmenides]] and later Greek philosopher [[Sextus Empiricus]], and perhaps some Eastern philosophers. [[George Santayana]], in his ''Scepticism and Animal Faith'', attempted to show that the reality of change cannot be proven. If his reasoning is sound, it follows that to be a physicist, one must restrain one's skepticism enough to trust one's senses. |
