Is there not one true coin for which all things ought to exchange?- and that is wisdom; and only in exchange for this, and in company with this, is anything truly bought or sold, whether courage, temperance or justice. And is not all true virtue the companion of wisdom, no matter what fears or pleasures or other similar goods or evils may or may not attend her? But the virtue which is made up of these goods, when they are severed from wisdom and exchanged with one another, is a shadow of virtue only, nor is there any freedom or health or truth in her; but in the true exchange there is a purging away of all these things, and temperance, and justice, and courage, and wisdom herself, are a purgation of them.

Do you feel no compunction, Socrates, at having followed a line of action which puts you in danger of the death penalty?' I might fairly reply to him, 'You are mistaken, my friend, if you think that a man who is worth anything ought to spend his time weighing up the prospects of life and death. He has only one thing to consider in performing any action--that is, whether he is acting rightly or wrongly, like a good man or a bad one.

"A fixed money supply, or a supply altered only in accord with objective and calculable criteria, is a necessary condition to a meaningful just price of money." —Fr. Bernard W. Dempsey, S.J.

"First, there are no bitcoins. There just aren’t. They don’t exist. There are ledger entries in a ledger that’s shared […] They don’t exist in any physical location. The ledger exists in every physical location, essentially. Geography doesn’t make sense here." —Peter Van Valkenburgh
