Plato. It was requisite to dispel the mists of ignorance and error.
Diogenes. Has he done it? What doubt has he elucidated, or what fact has he established? Although I was but twelve years old and resident in another city when he died, I have taken some pains in my inquiries about him from persons of less vanity and less perverseness than his disciples. He did not leave behind him any true philosopher among them; any who followed his mode of argumentation, his subjects of disquisition, or his course of life; any who would subdue the malignant passions or coerce the looser; any who would abstain from calumny or from cavil; any who would devote his days to the glory of his country, or, what is easier and perhaps wiser, to his own well-founded contentment and well-merited repose. Xenophon, the best of them, offered up sacrifices, believed in oracles, consulted soothsayers, turned pale at a jay, and was dysenteric at a magpie.
Plato. He had courage at least.
Diogenes. His courage was of so strange a quality, that he was ready, if jay or magpie did not cross him, to fight for Spartan or Persian. Plato, whom thou esteemest much, and knowest somewhat less, careth as little for portent and omen as doth Diogenes. What he would have done for a Persian I cannot say; certain I am that he would have no more fought for a Spartan than he would for his own father: yet he mortally hates the man who hath a kinder muse or a better milliner, or a seat nearer the minion of a king. So much for the two disciples of Socrates who have acquired the greatest celebrity!
Plato. Diogenes! if you must argue or discourse with me, I will endure your asperity for the sake of your acuteness; but it appears to me a more philosophical thing to avoid what is insulting and vexatious, than to breast and brave it.
Diogenes. Thou hast spoken well.
Plato. It belongs to the vulgar, not to us, to fly from a man’s opinions to his actions, and to stab him in his own house for having received no wound in the school. One merit you will allow me: I always keep my temper; which you seldom do.
Diogenes. Is mine a good or a bad one?
Plato. Now, must I speak sincerely?
