other, it must follow by consequence that the other contrary must answer to
the remanent opposite to that wherewith it is conferred. As, for example,
virtue and vice are contrary in one kind, so are good and evil. If one of
the contraries of the first kind be consonant to one of those of the
second, as virtue and goodness, for it is clear that virtue is good, so
shall the other two contraries, which are evil and vice, have the same
connection, for vice is evil.

This logical rule being understood, take these two contraries, joy and
sadness; then these other two, white and black, for they are physically
contrary. If so be, then, that black do signify grief, by good reason then
should white import joy. Nor is this signification instituted by human
imposition, but by the universal consent of the world received, which
philosophers call Jus Gentium, the Law of Nations, or an uncontrollable
right of force in all countries whatsoever. For you know well enough that
all people, and all languages and nations, except the ancient Syracusans
and certain Argives, who had cross and thwarting souls, when they mean
outwardly to give evidence of their sorrow, go in black; and all mourning
is done with black. Which general consent is not without some argument and
reason in nature, the which every man may by himself very suddenly
comprehend, without the instruction of any--and this we call the law of
nature. By virtue of the same natural instinct we know that by white all
the world hath understood joy, gladness, mirth, pleasure, and delight. In
former times the Thracians and Cretans did mark their good, propitious, and
fortunate days with white stones, and their sad, dismal, and unfortunate
ones with black. Is not the night mournful, sad, and melancholic? It is
black and dark by the privation of light. Doth not the light comfort all
the world? And it is more white than anything else. Which to prove, I
could direct you to the book of Laurentius Valla against Bartolus; but an
evangelical testimony I hope will content you. Matth. 17 it is said that,
