As to the issue between monotheism and trinitarianism, it has long since become obsolescent, if not obsolete. The forward-looking men and women of our time are absorbed in far other issues—Is the mechanical theory propounded by science the ultimate account of things? Is the world in which we live a blind machine? Is man a chance product of nature, like the beasts that perish? Not is God one in unity or is He a Triune God, but, is there a God at all? Is there a supersensible reality? Is religion capable of a new lease of life, and of giving a new lease of life to us who now are spiritually dead? [10] Of many ethical types of behavior no examples whatever as yet exist, for instance, of the ethically-minded employer or merchant, ethically-minded in thought and in practice. The standard of ethical behavior which we apply is at present higher and more exacting. The standard itself indeed is in process of being defined, and there are no illustrations of it, or none but very imperfect ones, on which to dwell with satisfaction. But the same is true of other vocations. We are very thankful for any examples that can be found. They seem to prove that that which ought to be can be. But we may not lean on them too hard. They are never quite adequate, even in their limited sphere; and there is ever an Ought-to-be beyond that which has been even partially realized, beyond that which has even as yet been conceived. To make too much of example is to check moral progress. Along with a due appreciation of past moral achievements, there should be encouraged a spirit of brave adventure, a certain intrepidity of soul to venture forth on voyages of discovery into unknown ethical regions, taking the risks but bent upon the prize.
