““Nothing is richer than precious stones and than gold; nothing is finer than adamant, nothing nobler than the blood of kings; nothing is sacred in wars; nothing is greater than Socrates' wisdom - indeed, by his own affirmation, nothing is Socrates' wisdom. Nothing is the subject of the speculations of the great Zeno; nothing is higher than heaven; nothing is beyond the walls of the world; nothing is lower than hell, or more glorious than virtue.””
