Such a conception of God, as a perpetual Creator, is essential to the intellectual rest of the human mind, and it is painful to see the irresolution of Professor Tyndall in regard to it. "Clear and confident as Jove" in the domain which is his own, where his masterly powers of observation, discrimination, and judgment leave him without a peer, he seems shorn of his strength on entering this field of metaphysics. He has warned theology not to trespass on the grounds of science; or, if she enters them, to submit to science as her superior. Theology has been in the habit of treating science in the same supercilious way; telling her that she was an intruder if she ventured to discuss questions of psychology or religion. This is equally unwise on either part. Theologians should be glad when men of science become seriously interested in these great questions of the Whence and the Whither. The address of Professor Tyndall is excellent in its intention as well as in its candid and manly treatment of the subject. Its indecision and indistinctness are probably due to his having accepted too implicitly the guidance of Spencer, thus assuming that religious truth is unknowable, that creation is impossible, and that only phenomena can become objects of knowledge. "Insoluble mystery" is therefore his final answer to the questions he has himself raised. Goethe is wiser when he follows the Apostle Paul, and regards the Deity as "the fullness which filleth all in all." There is no unity to thought, and no hope for scientific progress, more than for moral culture, unless we see intelligence at the centre, intelligence on the circumference of being. To place an impenetrable darkness instead of an unclouded light on the throne of the universe, is to throw a shadow over the Creation. We say that there is no unity in thought without this conviction. The only real unity we know in the world is our own. All we see around us, including our own body, is divisible, subject to alteration and change. Only the ego, or soul, is conscious of a perfect unity in a perpetual identity. Unless we can attribute to the source of all being a similar personal unity, there can be no coherence to science, but it must forever remain fragmentary and divided. This is what we mean by asserting the personality of Deity. This idea reaches what Lord Bacon calls "the vertical point of natural philosophy" or "the summary law of Nature," and constitutes, as he declares, "the union of all things in a perpetual and uniform law." And unless we can recognize in the ultimate fountain of being an intelligent purpose, the meaning of the universe departs. Without intelligence in the cause there is none in the effect. Then the world has no meaning, life no aim. The universe comes out of darkness, and is plunging into darkness again.
