It tells us that not one of the operations of the mind or manifestations of inner sense can be explained on materialistic lines; that, accordingly, no illuminating or determining judgement as to the separate nature of what thinks, or of the continuance or discontinuance of its personality after death, can possibly be made on speculative grounds by any exercise of our faculty of theoretical knowledge, Thus everything is here left to the teleological judging of our existence from a point of view that is necessary in the practical sphere, and to the assumption of the continuance of our existence, as a condition required by the final end that is absolutely imposed upon us by reason.
