Abstract
William Albert Crawford-Frost was a Canadian born philosopher who developed a unique form of idealism that he called the Philosophy of Integration. This he presented in 1906 in a book by that title which he described in the subtitle as An Explanation of the Universe and of the Christian Religion. What I have taken the liberty of calling his Fusion Philosophy is the metaphysical theory outlined in this work as explained and developed further in his two other books, Old Dogma in a New Light, and A New Theory of Evolution, as well as in a number of shorter pamphlets. I am using the term “fusion” rather than “integration” partly to avoid the social and political emphasis which the latter word has since acquired. However, I am not at all unhappy that my term “fusion” calls to mind our developing nuclear technology since, as will be seen, it is an implication of Crawford-Frost’s idealism that the development and application of nuclear fission, as opposed to fusion, is quite literally nothing less than the work of the Devil. This makes Crawford-Frost’s philosophy of some interest to us today, though I think that his unique form of idealism is, in many ways, interesting in itself.
