“And therefore if the head and the body are to be well, you must begin by curing the soul; that is the first and essential thing. And the care of the soul, my dear youth, has to be effected by the use of certain charms, and these charms are fair words; and by them temperance is implanted in the soul, and where temperance comes and stays, there health is speedily imparted, not only to the head, but to the whole body.”

“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.”

“I thought that as I had failed in the contemplation of true existence, I ought to be careful that I did not lose the eye of my soul; as people may injure their bodily eye by observing and gazing on the sun during an eclipse, unless they take the precaution of looking at the image reflected in the water, or in some similar medium. ...I was afraid that my soul might be blinded altogether if I looked at things with my eyes or tried by the help of my senses to apprehend them. And I thought that I had better had recourse to ideas, and seek in them truth in existence. I dare to say that the simile is not perfect--for I am far from admitting that he who contemplates existence through the medium of ideas, sees them only "through a glass darkly," any more than he who sees them in their working and effects.”

“I honor and love you: but why do you who are citizens of the great and mighty nation care so much about laying up the greatest amount of money and honor And reputation, and so little amount wisdom and truth and the greatest improvement of the soul? Re you not ashamed of these?... I do nothing but go about persuading you all, not to take thought for your persons and your properties, but first and chiefly to care about the greatest improvement of the soul. I tell you that virtue is not given by more, but that from virtue comes money and every other good of man. ”

“Are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?”

“All men's souls are immortal, but the souls of the righteous are immortal and divine.”

“Are you not ashamed of heaping up the greatest amount of money and honour and reputation, and caring so little about wisdom and truth and the greatest improvement of the soul? ”
