virtue and vice are like life and death, or mind and matter—things which cannot exist without being qualified by their opposite.

Context

“People divide off vice and virtue as though they were two things, neither of which had with it anything of the other. This is not so. There is no useful virtue which has not some alloy of vice, and hardly any vice, if any, which carries not with it a little dash of virtue; virtue and vice are like life and death, or mind and matter—things which cannot exist without being qualified by their opposite. The most absolute life contains death, and the corpse is still in many respects living; so also it has been said, “If thou, Lord, wilt be extreme to mark what is done amiss,” which shows that even the highest ideal we can conceive will yet admit so much compromise with vice as shall countenance the poor abuses of the time, if they are not too outrageous.” source
