Here my criticism might properly have ended, were it not that Mr. Fiske, after having divested the Deity of all his psychical attributes, forthwith proceeds to show how it may be dimly possible to reinvest him with attributes that are "quasi-psychical." Mr. Fiske is, of course, far too subtle a thinker not to see that his previous argument from relativity precludes him from assigning much weight to the ontological speculations in which he here indulges, seeing that in whatever degree the relativity of knowledge renders legitimate the non-ascription to Deity of known psychical attributes, in some such degree at least must it render illegitimate the ascription to Deity of unknown psychical attributes. But in the part of his work in which he treats of the quasi-psychical attributes, Mr. Fiske is merely engaged in showing that the speculative standing of the "materialists" is inferior to that of the "spiritualists;" so that, as this is a subject distinct from Theism, he is not open to the charge of inconsistency. Well, feeble as these speculations undoubtedly are in the support which they render to Theism, it nevertheless seems desirable to consider them before closing this review. The speculations in question are quoted from Mr. Spencer, and are as follows:-- "Mind, as known to the possessor of it, is a circumscribed aggregate of activities; and the cohesion of these activities, one with another, throughout the aggregate, compels the postulation of a something of which they are the activities. But the same experiences which make him aware of this coherent aggregate of mental activities, simultaneously make him aware of activities that are not included in it--outlying activities which become known by their effects on this aggregate, but which are experimentally proved to be not coherent with it, and to be coherent with one another (_First Principles_, Sec.Sec. 43, 44). As, by the definition of them, these external activities cannot be brought within the aggregate of activities distinguished as those of Mind, they must for ever remain to him nothing more than the unknown correlatives of their effects on this aggregate; and can be thought of only in terms furnished by this aggregate. Hence, if he regards his conceptions of these activities lying beyond Mind as constituting knowledge of them, he is deluding himself: he is but representing these activities in terms of Mind, and can never do otherwise. Eventually he is obliged to admit that his ideas of Matter and Motion, merely symbolic of unknowable realities, are complex states of consciousness built out of units of feeling. But if, after admitting this, he persists in asking whether units of feeling are of the same nature as the units of force distinguished as external, or whether the units of force distinguished as external are of the same nature as units of feeling; then the reply, still substantially the same, is that we may go further towards
