With this we have the outlines of a philosophy of pure experience before us. At the outset of my essay, I called it a mosaic philosophy. In actual mosaics the pieces are held together by their bedding, for which bedding the Substances, transcendental Egos, or Absolutes of other philosophies may be taken to stand. In radical empiricism there is no bedding; it is as if the pieces clung together by their edges, the transitions experienced between them forming their cement. Of course such a metaphor is misleading, for in actual experience the more substantive and the more transitive parts run into each other continuously, there is in general no separateness needing to be overcome by an external cement; and whatever separateness is actually experienced is not overcome, it stays and counts as separateness to the end. But the metaphor serves to symbolize the fact that Experience itself, taken at large, can grow by its edges. That one moment of it proliferates into the next by transitions which, whether conjunctive or disjunctive, continue the experiential tissue, can not, I contend, be denied. Life is in the transitions as much as in the terms connected; often, indeed, it seems to be there more emphatically, as if our spurts and sallies forward were the real firing-line of the battle, were like the thin line of flame advancing across the dry autumnal field which the farmer proceeds to burn. In this line we live prospectively as well as retrospectively. It is 'of' the past, inasmuch as it comes expressly as the past's continuation; it is 'of' the future in so far as the future, when it comes, will have continued _it_. These relations of continuous transition experienced are what make our experiences cognitive. In the simplest and completest cases the experiences are cognitive of one another. When one of them terminates a previous series of them with a sense of fulfilment, it, we say, is what those other experiences 'had in view.' The knowledge, in such a case, is verified; the truth is 'salted down.' Mainly, however, we live on speculative investments, or on our prospects only. But living on things _in posse_ is as good as living in the actual, so long as our credit remains good. It is evident that for the most part it is good, and that the universe seldom protests our drafts.
