On the other hand there are people who produce no effect upon us whatever. They come and go with a like indifference. They are as unimportant psychically as if they were any other portion of the furniture. They never stir us. We might live with them for fifty years and be hardly able to tell, for any influence upon ourselves, whether they existed or not. They remind us of that neutral drab which certain religious sects assume to show their own irrelevancy to the world. They are often most estimable folk, but they are no more capable of inspiring a strong emotion than the other kind are incapable of doing so. And we say the difference is due to the personality or want of personality of the man. Now, in what does this so-called personality consist? Not in bodily presence simply, for men quite destitute of it possess the force in question; not in character only, for we often disapprove of a character whose attraction we are powerless to resist; not in intellect alone, for men more rational fail of stirring us as these unconsciously do. In what, then? In life itself; not that modicum of it, indeed, which suffices simply to keep the machine moving, but in the life principle, the power which causes psychical change; which makes the individual something distinct from all other individuals, a being capable of proving sufficient, if need be, unto himself; which shows itself, in short, as individuality. This is not a mere restatement of the case, for individuality is an objective fact capable of being treated by physical science. And as we know much more at present about physical facts than we do of psychological problems, we may be able to arrive the sooner at solution.
