Agnosticism

Spencer's reputation among the Victorians owed a great deal to his agnosticism. He rejected theology as representing the 'impiety of the pious.' He was to gain much notoriety from his repudiation of traditional religion, and was frequently condemned by religious thinkers for allegedly advocating atheism and materialism. Nonetheless, unlike Thomas Henry Huxley, whose agnosticism was a militant creed directed at 'the unpardonable sin of faith' (in Adrian Desmond 's phrase), Spencer insisted that he was not concerned with undermining religion in the name of science, but to bring about a reconciliation of the two. The following argument is a summary of Part 1 of his First Principles (2nd ed. 1867).

Starting either from religious belief or from science, Spencer argued, we are ultimately driven to accept certain indispensable but literally inconceivable notions. Whether we are concerned with a Creator or the substratum which underlies our experience of phenomena, we can frame no conception of it. Therefore, Spencer concluded, that religion and science agree in the supreme truth that human understanding is only capable of 'relative' knowledge. This is the case since, owing to the inherent limitations of the human mind, it is only possible to obtain knowledge of phenomena, not of the reality ('the absolute') underlying phenomena. Hence both science and religion must come to recognise as the 'most certain of all facts that the Power which the Universe manifests to us is utterly inscrutable.' He called this awareness of 'the Unknowable' and he presented worship of the Unknowable as capable of being a positive faith which could substitute for conventional religion. Indeed, he thought that the Unknowable represents the ultimate stage in the evolution of religion, the final elimination of its last anthropomorphic vestiges.
