Plato: Five Dialogues: Euthyphro, Apology, Crito, Meno, Phaedo

by Plato

Is the pious being loved by the gods because it is pious, or is it pious because it is being loved by the gods?

we will be better men, braver and less idle, if we believe that one must search for the things one does not [c] know, rather than if we believe that it is not possible to find out what we do not know and that we must not look for it.
