Let us therefore inquire, not what is most commonly done, but what is best for us to do, and what will establish us in the possession of undying happiness, not what is approved of by the vulgar, the worst possible exponents of truth.
By “the vulgar” I mean both those who wear woollen cloaks and those who wear crowns;  for I do not regard the colour of the clothes with which they are covered: I do not trust my eyes to tell me what a man is: I have a better and more trustworthy light by which I can distinguish what is true from what is false: let the mind find out what is good for the mind.
If a man ever allows his mind some breathing space and has leisure for communing with himself, what truths he will confess to himself, after having been put to the torture by his own self!
He will say, “Whatever I have hitherto done I wish were undone: when I think over what I have said, I envy dumb people: whatever I have longed for seems to have been what my enemies would pray might befall me: good heaven, how far more endurable what I have feared seems to be than what I have lusted after.
I have been at enmity with many men, and have changed my dislike of them into friendship, if friendship can exist between bad men: yet I have not yet become reconciled to myself.
I have striven with all my strength to raise myself above the common herd, and to make myself remarkable for some talent: what have I effected save to make myself a mark for the arrows of my enemies, and show those who hate me where to wound me?
Do you see those who praise your eloquence, who covet your wealth, who court your favour, or who vaunt your power?
All these either are, or, which comes to the same thing, may be your enemies: the number of those who envy you is as great as that of those who admire you; why do I not rather seek for some good thing which I can use and feel, not one which I can show? these good things which men gaze at in wonder, which they crowd to see, which one points out to another with speechless admiration, are outwardly brilliant, but within are miseries to those who possess them.”
