But, more than this, a trusty councillor has been assigned us, who is independent of our wills, and bears credentials from God Himself. Conscience is an incorruptible and infallible judge, whom, if we will, we may hear pronounce sentence every moment, and whose voice at last reaches even those who most obstinately refuse to listen. The laws which human society has imposed upon itself can take account of actions only in their tribunals, and not of thoughts and feelings. Even the various religions make different demands among the different peoples. Here they require the Sunday to be kept holy, here the Saturday or Friday. One allows pleasures which another forbids. Even apart from these differences there is always a wide neutral ground between what is allowed and what is forbidden; and it is here that conscience, with her subtler discrimination, raises her voice. She tells us that _every_ day should be kept sacred to the Lord, that even permitted interest becomes unjust when exacted from the needy; in a word, she preaches morality in the bosom of Christian and Jew, of heathen and savage. For even among uncivilized races which have not the light of Christianity there is an agreement as to the fundamental conceptions of good and evil. They, too, recognize the breaking of promises, lying, treachery, and ingratitude as evil; they, too, hold as sacred the bond between parents, children, and kinsmen. It is hard to believe in the universal corruption of mankind, for, however obscured by savagery and superstition, there lies dormant in every human breast that feeling for the noble and the beautiful which is the seed of virtue, and a conscience which points out the right path. Can there be a more convincing proof of God's existence than this universal sense of right and wrong, this unanimous recognition of one law, alike in the physical and in the moral world, except that nature obeys this law with a full and absolute obedience, while man, who is free, has the power of violating it? The body and the reason serve the ruling part of the soul, but they put forward claims of their own, they have their own share of power, and thus man's life is a perpetual conflict with self. If in this conflict the soul, hard-pressed from within and without, does not always end by obeying the voice of conscience, let us hope that He who created us imperfect will not require perfection from us.
