Perhaps some one may ask: Why may not practical efficiency reside in the non-fluxional (or permanent)? If so, this is wrong, as obnoxious to the following dilemma. Has your "permanent" a power of past and future practical efficiency during its exertion of present practical efficiency or no? On the former alternative (if it has such power), it cannot evacuate such past and future efficiency, because we cannot deny that it has power, and because we infer the consequence, that which can at any time do anything does not fail to do that at that time, as, for instance, a complement of causes, and this entity is thus powerful. On the latter alternative (if the permanent has no such power of past and future agency), it will never do anything, because practical efficiency results from power only; what at any time does not do anything, that at that time is unable to do it, as, for instance, a piece of stone does not produce a germ; and this entity while exerting its present practical efficiency, does not exert its past and future practical efficiency. Such is the contradiction.
