We must be careful not to confound Theism with Deism, for though both are the same word--one Greek and one Latin--and mean the same thing, yet they stand for entirely different conceptions. Deism is a purely negative system, weighed down with denials. It is content when it has rejected what it calls all supernatural adjuncts--miracles, revelations, an inspired Scripture. Its face is set towards the past, not toward the future, and it is simply what is left of the old systems of belief, having no positive philosophy of its own. But Theism is a positive, fresh, original faith. It gazes forward, and builds on the natural consciousness of man, making no criticism on previous modes of belief. It is full of hope and enthusiasm, looking towards something that is before it, not scorning but believing. All that it needs in order to become a popular faith is a poetical element, something imaginative, symbolical, picturesque. The intellectual requirements it already possesses. It is affirmative; it is universal. Neither must this kind of theism be identified with natural religion, unless natural religion be made to comprehend facts of the inner as well as the outer world--facts of psychology as well as of physiology; facts of mind as well as of body. Such a theism is not a mere reminiscence, either, of an ancient faith; for every form of mediatorial religion, however modified, simplified, "enlightened," as it is called, leaves something of its temper behind it. The intellect is haunted by old modes of truth; the heart lingers around the ancient places of reverence; the conscience refers to some antique authority; the soul cannot pray except in the language of a pater-noster or a psalm. A scent as of roses may hang round the human mind; but the roses will be grown in some garden of the East, not in ours. Such a theism as I am thinking of will be grounded in Ethical Law. You may call it "Christian," if you will, because the word _Christian_ expresses the highest form of the moral sentiment, and carries a supreme authority to the human conscience; but on the _human conscience_ it must rest. It will be a noble, pure faith, giving a welcome to all knowledge, bright with anticipation, warm with enthusiasm. As John Weiss has said so much better than I can what I mean, I will quote a passage from him. It occurs in "American Religion" (page 67):
