The Metaphysical Society debates were largely between those espousing religious commitment to the transcendent and those defending scientific naturalism. However, this paper highlights a third strain of thought to be found among the Society’s proceedings, one which regarded philosophy – and especially metaphysics – as an autonomous discipline with its own method and authority. To this way of thinking the proper project of the Society was precisely to use such independent and constructive philosophy to seek for reconciliation between the opposed views of religion and science. The paper focuses on the pair of Society members who most strongly embody this point of view, Shadworth Hodgson (1832–1912) and William Kingdon Clifford, (1845–79) analysing their several contributions and, in particular, comparing their different responses to the theory set out in Peter Guthrie Tait and Balfour Stewart’s influential work, The Unseen World. (1875) Both thinkers see merit in the idea of an unseen realm. However, both relativize this ‘unseen’ to a point of view, thereby ruling out of court that which is utterly and completely unknowable. In this respect they are linked together in common opposition to one further widespread philosophy of the day, agnosticism. From an historical perspective neither Hodgson nor Clifford met with much popular or lasting success in their attempts at finding a philosophical reconciliation between religion and science, and the paper concludes by contrasting their efforts with those of the British Idealists who, seemingly, were able to achieve much greater recognition in what was in many respects a similarly motivated ambition.
