Courage

What I mean is courage is a kind of salvation. Socrates gives an illustration. “You know, he said, that dyers, when they want to dye wool for making the true sea-purple, begin by selecting their white color first; this they prepare and dress with much care and pains, in order that the white ground may take the purple hue in full perfection. The dyeing then proceeds and whatever is dyed in this manner becomes a fixed color, and no washing either with lyes or without them can take away the coloration.” Courage under all circumstances is the nature of things to be feared and not to be.

This is what Socrates termed courage, as indelibly fixed by nurture and training, not to be washed away by such potent lyes by sorrow, fear, and desire, pleasure they are all mighty solvents. Courage, this sort of universal saving power of true opinion in conformity with rules about real and false situations.
