The principal points in these objections are that abstract thought does not postulate being; and that possibly all intelligence is not one in kind. To the former objection the most satisfactory, reply has been offered by Professor J. F. Ferrier. He has shown that the conception of object, even ideal object, implies the conception of self in the subject; and upon this proposition which has been fully recognized even by those who differ from him widely, he grounds the existence of Supreme Thought as a logical unity. Those who would pursue this branch of the subject further, I would refer to his singularly able work.[43-1]
The latter consideration will come up in a later chapter. If it be shown that all possible intelligence proceeds on the same laws as that of man, and that the essence of this is activity, permanence, or truth—synonymous terms—then the limitation of time ceases, and existence not in time but without regard to time, is a necessary consequence. Knowledge through intellection can alone reach a truth independent of time; that through sensation is always relative, true for the time only. The former cannot be expressed without the implication of the conceptions of the universal and the eternal as “dominant among the subjects of thought with which Logic is concerned;”[44-1] and hence the relation which the intellect bears to the absolute is a real and positive one.
