Yet there have been philosophies which have tried to make of time a magical device by which man might represent to himself in succession that which in itself is never in succession. They picture his journey through life as a journey through space where all that he sees, one thing after another, comes successively into view like the houses on a street along which he may walk. But as the houses do not exist in succession, neither do the facts he discovers. They, too, come into view as he moves along. These philosophies, consequently, would have us think of a world in itself, absolute and complete, to which nothing can be added and from which nothing can be subtracted. It is somehow fixed and finished now; but our human experience, being incomplete and unfinished, gives to it the appearance of a process in time and discloses to us what it would be like if all its factors and the laws which hold them in perfect equilibrium were experienced in succession. History would thus be a kind of temporal revelation of the absolute and we should read it as we read a book, from cover to cover, discovering page by page a story which is itself finished when we begin. Or philosophy, when it has not conceived the world to be thus finished and complete in itself and only appearing to us as a temporal revelation, has often thought of movements in time as only the results of preceding movements. Whatever happens is thus conceived to be the effect of what has already happened, rather than the active conservation and working over of what has already happened. The past is made the cause and producer of the present, so that the state of the world at any moment is only the result or outcome of what it was in the preceding moment. To-day is thought to be the effect of yesterday and the cause of to-morrow, and is thus but a transition from one day to another. Time-processes are thus robbed of any genuine activity or productivity, and time itself is made to be nothing but the sequential order in which events occur. Purpose, conservation, utilization, and all that active supplementing and working over of the past on which we have dwelt, become illusions when applied to the world at large. They represent our way of conceiving things, but not nature's way of doing things.
