Then, besides that, conscience wants educating. You see that on a large scale, for instance, in the history of the slow progress which Christian principle has made in leavening the world's thinkings. It took eighteen centuries to teach the Church that slavery was unchristian. The Church has not yet learned that war is unchristian, and it is only beginning to surmise that possibly Christian principle may have something to say in social questions, and in the determination, for example, of the relations of capital and labour, and of wealth and poverty. The very same slowness of apprehension and gradual growth in the education of conscience, and in the perception of the application of Christian principles to duty, applies to the individual as to the Church. Then, besides that, we are all biassed in our own favour, and what, when another man says it, is 'flat blasphemy,' we think, when we say it, is only 'a choleric word.' We have fine names for our own vices, and ugly ones for the very same vices in other people. David will flare up into generous and sincere indignation about the man that stole the poor man's ewe lamb, but he has not the ghost of a notion that he has been doing the very same thing himself. And so we bribe our consciences as well as neglect them, and they need to be educated. Thus, down below every life there lies a great dim region of habits and impulses and fleeting emotions, into which it is the rarest thing for a man to go with a candle in his hand to see what it is like.
