You know the way in which dyers first prepare the white ground and then lay on the dye of purple or of any other colour.

Colours dyed in this way become fixed, and no soap or lye will ever wash them out.

Now the ground is education, and the laws are the colours; and if the ground is properly laid, neither the soap of pleasure nor the lye of pain or fear will ever wash them out.

This power which preserves right opinion about danger I would ask you to call 'courage,' adding the epithet 'political' or 'civilized' in order to distinguish it from mere animal courage and from a higher courage which may hereafter be discussed.
Two virtues remain; temperance and justice.

More than the preceding virtues temperance suggests the idea of harmony.
