In this view of causation, then, Powell advanced nothing new. But what he did advance was really valuable. The man who can rise no higher than law or succession as he sees it impressed on outward nature, stands in a totally different position from the man whose insight into Reason and Will has shown him the idea of true Causation. For, he has seen that whoever is the author of his own act, does something which puts in movement a new series of antecedence and consequence,--a new train of events, the issue of which no man can foresee;--though of what has come, and is coming, he, the individual man, is the truly responsible cause[s]. But if _he_ can introduce into the order of the outward world a new antecedent carrying after it a chain of new consequents, what shall he think respecting the absolute Cause of all worlds, things and beings, the thinker himself included? Who shall persuade him to deny the reasonableness of a Providence following creation? Who can reprove the man when he feels and asserts his own moral power, for a belief in Miracles? Above all, who will demonstrate that prayer is inefficacious, if we can rise (as Baden Powell says we can rise) "by _analogy_ with the exercise of intellect, and the volition, or power of moral causation, of which we are conscious within ourselves, to the Supreme Mind and Moral Cause of the universe?" It is no slight praise to say that Professor Powell clearly saw, and no less clearly expressed, a truth not always apprehended among physicists. By giving it expression, he rendered a substantial service to Natural Theology. It is, indeed, a serious drawback and impediment to Natural Theologians that their argument requires some acquaintance with more than one wide field of knowledge. They have to reason from the material world,--they have also to reason from the world of mind; and in countries like England, France, and Germany, where division of labour penetrates every calling, literary as well as manufacturing, a combination of this sort is a matter of infrequent occurrence. To this retarding circumstance may be ascribed the want of progress in several mixed sciences,[35] which, like the subject we are treating, occupy two distinct tracts of border-land territory. The separating wall between Law and Cause built up by Professor Powell, was founded on fact, and will probably remain unshaken. But he added to it a theoretical limitation of the term, Natural Theology, which, like many changes in verbal usage, does not appear defensible,--particularly as its bad effects are plainly shown in Professor Powell's own book.
