Here we reach the highwater mark of present day antitheistic thought. Our opponents maintain not only that they do not know anything about the nature of reality but that nobody else can possibly know anything about it. The present day scientist is often not the humble seeker after truth but the militant preacher of a faith, and the faith that he preaches is the faith of agnosticism. It is this point to which we have seen all things come. The face of science and philosophy today is, with rare exceptions, set squarely against Christianity and the Theism that serves it as a foundation.
What else, then, can we do but take the sword as well as the trowel? We are driven to a defense of our faith. The full-orbed life, that which the world has sought in vain, is in our possession. We have an absolute God in whose fellowship we have even now the full-orbed life. We have an absolute God who alone can give meaning to all our strivings for advancement. We have an absolute God who alone can guarantee that that which we have in principle now will be fully realized hereafter.
