Religious questions have often led to wicked and impious actions.

(On the temperature of water in wells) The reason why the water in wells becomes colder in summer is that the earth is then rarefied by the heat, and releases into the air all the heat-particles it happens to have. So, the more the earth is drained of heat, the colder becomes the moisture that is concealed in the ground. On the other hand, when all the earth condenses and contracts and congeals with the cold, then, of course, as it contracts, it squeezes out into the wells whatever heat it holds.

Even if I knew nothing of the atoms, I would venture to assert on the evidence of the celestial phenomena themselves, supported by many other arguments, that the universe was certainly not created for us by divine power: it is so full of imperfections.

You alone govern the nature of things. Without you nothing emerges into the light of day, without you nothing is joyous or lovely.

All things obey fixed laws.
