=Time and its treasure.=--Taking the modern estimates of the physicists, we are assured that the total period of past human existence is very brief compared with what may reasonably be predicted. Granted, then, practically unlimited time, what inherent limits are there to the upward development of man as a moral and intellectual being? Shall we answer this question by a study of the nature of matter? Plainly not. Shall we answer it by a study of the nature of mind? Surely not, for the study of existing mind cannot inform us as to what mind might be. One source of guidance alone we have, and this is the amazing contrast which exists between the mind of man at its highest, and mind in its humblest animal forms: or shall we say even between the highest and lowest manifestations of mind within the human species? The measureless height of the ascent thus indicated offers us no warrant for the conclusion that, as we stand on the heights of our life, our “glimpse of a height that is higher” is only an hallucination. On the contrary. There is no warrant whatever for supposing that the forces which have brought us thus far are yet exhausted: they have their origin in the inexhaustible. Who, gazing on the earth of a hundred million years ago, could have predicted life--could have recognised, in the forces then at work and the matter in which they were displayed, the promise and potency of all terrestrial life? Who, contemplating life at a much later stage, even later mammalian, could have seen in the simian the prophecy of man? Who, examining the earliest nervous ganglia, could have foreseen the human cerebrum? The fact that we can imagine nothing higher than ourselves, that we make even our gods in our own image, offers no warrant for supposing that nothing higher will ever be, What ape could have predicted man, what reptile the bird, what amœba the bee? “There are many events in the womb of time which will be delivered,” and the fairest of her sons and daughters are yet to be.
