7. But it is moreover wholly evident, that we may apply this argument to all those things which are called and esteemed bitter, sweet, purging, dormitive, and luminous, not any one of them having an entire and perfect quality to produce such effects, nor to do rather than to suffer when they are in the bodies, but being there susceptible of various temperatures and differences. For Epicurus himself, in his Second Book against Theophrastus, affirming that colors are not connatural to bodies, but are engendered there according to certain situations and positions with respect to the sight of man, says: “For this reason a body is no more colored than destitute of color.” And a little above he writes thus, word for word: “But apart from this, I know not how a man may say that those bodies which are in the dark have color; although very often, an air equally dark being spread about them, some distinguish diversities of colors, others perceive them not through the weakness of their sight. And moreover, going into a dark house or room, we at our first entrance see no color, but after we have stayed there awhile, we do. Wherefore we are to say that every body is not more colored than not colored. Now, if color is relative and has its being in regard to something else, so also then is white, and so likewise blue; and if colors are so, so also are sweet and bitter. So that it may truly be affirmed of every quality, that it cannot more properly be said to be than not to be. For to those who are in a certain manner disposed, they will be; but to those who are not so disposed, they will not be.” Colotes therefore has bedashed and bespattered himself and his master with that dirt, in which he says those lie who maintain that things are not more of one quality than another. 8. But is it in this alone, that this excellent man shows himself To others a physician, whilst himself Is full of ulcers?[127]
