selfish, or sensual motives, though some hide their motives better than others, or have feelings and likings of a more refined character. And having given in to sin themselves, they have no higher principle within them to counteract the effect of what they see without; all their notions of man's nature, capabilities, and destinies, are derived from, and are measured by, what goes on in the world, and accordingly they apply all their knowledge to bad purposes. They think they know, and they do know too truly on the whole, the motives and inducements which will prevail with men; and they use their knowledge to overreach, deceive, seduce, corrupt, or sway those with whom they have to do. 4. Another very different class of persons who study evil, and pride themselves upon it, and are degraded by it, are those who indulge themselves in contemplating and dwelling on the struggle between right and wrong in their own minds. There have been from time to time men of morbid imaginations, of any or no religious creed, who have so exercised themselves. Indeed there has been a large school of writers in very various departments, for years, I may say centuries past, though happily they are diminishing now, who delight in bringing out into open day all the weaknesses and inconsistencies of human nature; nay worse, take pains to describe bad men, and how they feel, and what they say; who interest the mind in bad men, nay in bad Angels, as if Satan might be thought of otherwise than with shuddering. And there are others, men of mistaken religious views, who think that religion consists in dwelling on and describing the struggle between grace and corrupt nature in the soul. Christ has brought us light and life, and would have us put off what we are, and follow Him, who knew no sin. But these men, far from rising even to the aspiration after perfection, do not advance in their notion of spiritual religion beyond the idea of declaring and lamenting their want of it. Confession is with them perfection; nay, it is almost the test of a Christian, to be able to discourse upon his inward corruption. It is well to confess sin in detail with shame as an act of penitence; it is a snare to speak of it vaguely and in public.
