Agnosticism, in fact, is not a creed, but a method, the essence of which lies in the rigorous application of a single principle ... In matters of the intellect do not pretend that conclusions are certain which are not demonstrated or demonstrable.

→ Thomas Henry Huxley

...true Agnosticism will not forget that existence, motion, and law-abiding operation in nature are more stupendous miracles than any recounted by the mythologies, and that there may be things, not only in the heavens and earth, but beyond the intelligible universe, which "are not dreamt of in our philosophy."

→ Thomas Henry Huxley
