For it is unknown what is the real nature of the soul, whether it be born with the bodily frame or be infused at the moment of birth, whether it perishes along with us, when death separates the soul and body, or whether it visits the shades of Pluto and bottomless pits, or enters by divine appointment into other animals.
LucretiusEven 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.
LucretiusUnder what law each thing was created, and how necessary it is for it to continue under this, and how it cannot annul the strong rules that govern its lifetime.
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.
Lucretius
