The moral law proclaimed by Moses three thousand years ago agrees with that which governs men to-day, irrespective of their various stages of culture; the moral precepts of a Buddha and Confucius agree with those of the Gospel, and the sins for which, according to the Book of the Dead of the ancient Egyptians, men will answer to the judges of the other world are sins still after four thousand years. If the nature of the unknown First Cause is ever to be grasped at all, it can only be in the light of those unchanging moral principles which every man carries in his own breast. The idea of God is therefore not an affair of the understanding, but of the feeling and conscience. Mysticism has always so taken it, and has therefore always had a strong attraction for the excitable and emotional portion of mankind whom it has comforted in trial and affliction. Every religion is accordingly rather intended for the emotions than for the understanding, and therefore they all contain mystical tendencies.
