Why shed tears that you must die? For if your past life has been one of enjoyment, and if all your pleasures have not passed through your mind, as through a sieve, and vanished, leaving not a rack behind, why then do you not, like a thankful guest, rise cheerfully from life's feast, and with a quiet mind go take your rest.
LucretiusNo single thing abides; but all things flow. Fragment to fragment clings - the things thus grow Until we know them and name them. By degrees They melt, and are no more the things we know.
Lucretius(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.
LucretiusPoor humanity, to saddle the gods with such a responsibility and throw in a vindictive temper. What griefs they hatch for themselves, what festering sores for us, what tears for our prosperity! This is not piety, this oft-repeated show of bowing a veiled head before a graven image; this bustling to every altar; this kow-towing and prostration on the ground with palms outspread before the shrines of the gods; this deluging of vow on vow. True piety lies rather in the power to contemplate the universe with a quiet mind.
