I said I should be abstruse, and I have not yet finished. In fully appraising agnosticism we need to consider at close range another idea of the positivist. Thus for the positivist knowledge is not a having, but a getting--on the principle that unto him that hath shall be given; not a knowing, but a questioning and seeking; not a being, but a becoming--that has its ground in a being so real as to be without fixity of form. And this is plainly equivalent to making movement and action essential to the very nature of the knowing mind or to making knowledge dynamic instead of static, and infinitely plastic--even like life itself, that is always greater than its cross-sections or specific forms. But in general to an active nature nothing can ever be quite external; to a truly active nature there can be no essential impossibility. For reflect. The mere existence of anything external or of anything impossible would in just so far remove and deny the intrinsic character of the activity; in just so far it would set the supposedly active being in fixity of life and definiteness of form. For an essentially active nature, therefore, all things--all things in heaven and earth--are both present and possible, and so, specifically, if that active nature be the knowing mind there can be no unknowable that is at the same time alien and altogether impossible to the knower. Even the very forms of the knower's knowledge must for ever compass [p.125] pass more than they may visibly present. The knowing itself in its own right and nature must be more than formal knowing, or than the "objective," "special" science, in which the formal knowing has its professional realization. And the knower, as he knows, in and through his knowledge must always be compassing just that which is not impossible to him, but only unknowable--that is, impossible merely to his direct, formal knowledge. Is the inedible or the invisible or the impenetrable or the unbearable or the illegible or even the unintelligible ever wholly impossible? Such negatives, and in fact all negatives, besides saving life from the narrowness of its various forms, do this positive thing: they open the door of life's wider, nay, of life's infinite opportunity or possibility, and at the same time they render those various definite forms really mediative or instrumental, making them parts in an essentially purposive existence. With just this meaning, then, a meaning larger and deeper than that usual to positivism, the attitude of the agnostic is instrumental and teleological. Agnosticism simply endows the knower--must we not even put our conclusion so?--with a wider freedom than that of knowledge, and yet also makes his knowledge both share and serve the wider freedom that is given.
