As for causation our temerity is not less surprising. Wet and dry moons, unlucky Fridays, holy and unholy numbers, haunted houses, so-called providences, free in the sense of indifferently, irresponsibly free wills and fiat deities with their suddenly made worlds may not be generally in vogue at the present time, at least among the better educated, the enlightened and not infrequently conceited classes, but even among the wise and the consciously informed they have their natural offspring, and I am not so sure that many of them might not be found almost intact, at least in the more retired parts of the consciousness of my readers. To illustrate, for some if not for all of us, this is a world of many free and independent causes, yet also it is the single effect of one cause; it is again, our mood having changed, the single effect of two absolutely unlike beings or natures, each of them an all-powerful cause; it is a sphere here and now of causal, creative, productive activity, but it was itself created once for all long ago, at a date which the exegete hopes--in the equally distant future!--to determine for us; it contains some things that are only causes and some that are only effects, or some, or all, that are both causes and effects; it has parts that are the accepted causes of other parts; it has causes, those acting now and the one original cause, that are temporally [p.040] antecedent to their effects; and, not to make the list longer, it is variously a world of one last effect, of one first and only cause, of an infinite series of causes and effects, and in whole, or in part, it constantly shows something made out of nothing or nothing resulting from something. A wondrous world most assuredly; and yet at first statement this record of our various notions of causation may not appear as a very serious arraignment of the consciousness which it exposes. Moreover some people actually glory in such a wonder as it presents. But, to be plain, though also monotonous, the uncaused cause or the effect that is only a part of the whole, or the cause or the effect that refuses to share in the other's nature, or finally the causation that is now so individual and so manifold and so effective, and that was once so single and so complete, is something that must give any thinker pause. Can a moving body move an immobile body? Can some things in the universe be mobile; others not? Can the moving body and the moved body belong to different moments of time? Can motion lead to rest or rest to motion? But our ordinary ideas of causation would allow, or even require, an affirmative answer to every one of these questions.
