Newton's proof of the law of refraction is based on an erroneous notion that light travels faster in glass than in air, the same error that Descartes had made. This error stems from the fact that both of them thought that light was corpuscular in nature.

Empedocles tried to address the problem of change by saying that there is not one fundamental arche but four—earth, water, air, and fire—which generate all the material substances in nature by mixing together in various ways under the influence of forces he called Love and Strife.

Parmenides believed that all Being is what he called the One, and denied absolutely the possibility of change. He believed that the cosmos is full (i.e., no void), uncreated, eternal, indestructible, unchangeable, immobile sphere of being, and all sensory evidence to the contrary is illusory.
