True piety lies rather in the power to contemplate the universe with a quiet mind.

Epicurus ... whose genius surpassed all humankind, extinguished the light of others, as the stars are dimmed by the rising sun.

Religious questions have often led to wicked and impious actions.

The highest summits and those elevated above the level of other things are mostly blasted by envy as by a thunderbolt.

Pleasant it is, when over a great sea the winds trouble the waters, to gaze from shore upon another's great tribulation: not because any man's troubles are a delectable joy, but because to perceive from what ills you are free yourself is pleasant.

No matter how difficult a task may look.. Persistence and steady action will get you through

(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.
