recurrence, but complete and invariable recurrence) is the very foundation of science. Without it there can be no scientific laws, and without such laws--_i.e._, without records of past recurrences--there can be no sure predictions as to the future. It is only because certain motions of certain bodies have hitherto been observed to take place with invariable regularity, that they are expected to continue to do so, and it is upon that assumption only that we venture to predict that the sun will rise to-morrow morning, or that an eclipse will take place next year. But if no event recorded in history has ever yet been known to occur twice under precisely the same conditions, and as a consequence of the same causes, what ground can there be for predicting whether or when any such event will occur again? What possibility is there of constructing a science of history, when history supplies no materials for either foundation or superstructure? There is nothing in this conclusion in the slightest degree opposed to the most approved doctrine of causation. No effect can be without a cause. No doubt, then, the regency of invariable causation holds good of human volitions. No doubt the volitions and consequently the actions of men are the joint results of the external circumstances amid which men are placed, and of their own characters; which again are the results of circumstances, natural and artificial. So much must needs be admitted, and something more besides. Certain causes will infallibly be succeeded by certain effects. From any particular combination of circumstances, certain determinate consequences and no others will result; those again will give rise to consequences equally determinate, and those in turn to others, and so on in an infinite series. It follows, then, from the regency of causation, that there is a determinate course already, as it were, traced out, which human events will certainly follow to the end of time; every step of which course, however remote, might now be foreseen and predicted by adequate, that is to say by infinite, intelligence. Infinite intelligence would do this, however, not by the aid of law, but by virtue of its own intrinsic and unassisted strength, wherewith it would perceive how each succeeding combination of causes would operate. For, as cannot be too often repeated, a law is merely a record of recurrences; and in human affairs there can be no recurrences of the same aggregate either of causes or results. There being then no historic laws, there can be no Science of History, for science cannot exist without laws. The historic prescience, which is an attribute of Infinite Intelligence, not being regulated by law, or at any rate not by any law except that of causation, is not, technically speaking, a science, and even if it were, would be utterly beyond the reach of human intellect and attainable only by Infinite Wisdom.
