"I agree with Herbert Spencer in believing that thought derives its laws from that universe of things whereof the Mind is a part ; and from this I further infer that our spontaneous conceptions agree with the reality of things, and that our knowledge has a rational basis. This escape from Agnosticism seems perfectly satisfactory ; so that the philosophy of Evolution, though it is despised as being materialistic, affords a basis for belief ; while those idealistic systems whereof Kant's is the type, which are constructed out of the mind itself, notwithstanding their vast pretensions to spirituality, lead by a direct and logical path to absolute theoretical scepticism. And if the intuitions of our Intelligence in relation to the external and visible world are true, we may consistently trust the intuitions of our moral and spiritual intelligence, which testify to the absolute difference between moral good and evil, and to the imperative character of the moral sense."
