There is, perhaps, one other topic on which agnosticism may be professed, and that is in connection with the question of what is known as the problem of existence. We may profess our belief in the reality of an external world, but deny that any knowledge of it is possible. Here we assert that what “substance,” or “reality,” or “thing in itself,” is we do not know and cannot know. But while many attempts are made under the name of “the Absolute,” etc., to identify this with “God,” it is really nothing of the kind. The belief or disbelief in an external “reality” is a problem in philosophy, it has no genuine connection with theology. To identify the two is a mere dialectical subterfuge. Mere existence is an ultimate fact that must be accepted by all. It is only on the question of its nature that controversy can arise.
Whatever may be claimed on behalf of Agnosticism, it certainly cannot be claimed that it carries a clear and a definite meaning. As we have seen, Professor Huxley used the word to indicate the fact that he was without knowledge of certain things. But what things? To answer that we have to go beyond the word itself–that is, we have to define the definition. As it stands we may profess agnosticism in relation to anything from the prospects of a general election within a given period to the question of whether Mars is inhabited or not. If, then, it is said that what is implied is that the Agnostic is without a knowledge of God, or without a belief in God, the reply is that is exactly the position of the Atheist. And there was no need whatever to coin a new word, if all that was wanted was to express the atheistic position. Still less justifiable was it to proceed to misinterpret Atheism in order to justify a departure that need never have been made.
