Such reflections, however, only show that our limited insight is insufficient to assign to every appearance with certainty its own place in the ordered system of appearances through which the single Reality expresses itself. They do not touch our general position, that where comprehensiveness and harmony _can_ be seen to go together, we are justified in using them as the measure of the individuality and therefore of the reality of the partial system in which we discover them. It is on such grounds, for instance, that we may safely pronounce that an organism, which is the living unity of its members, is more individual and therefore a higher reality that a mere aggregate of pre-existing units, in which the nature of the parts is wholly or mainly independent of the structure of the whole; and again, that a mind consciously and systematically pursuing a coherent self-chosen system of ends is more individual, and therefore again a higher reality, than an organism reacting according to the temporary character of its environment or its momentary internal condition in ways which form no systematic execution of a connected scheme of ends. And it is clear that, if only on this ground, we should have to say that we are nearer the truth in thinking of the individual whole of complete Reality as an organism than in thinking of it as an aggregate, and nearer the truth still in thinking of it as a mind. Similarly in our judgments upon our own lives and character. So far as one life possesses more breadth and again more conscious unity of aim than another, so far it is more truly individual, and therefore a more adequate type of complete reality. Just so far as I am individual, I am truly real. And just so far as I fall short of systematic individuality, whether from the poverty of my interests or their mutual incompatibility, the appearance of unity in my life is illusory, and I must be pronounced an unreal appearance.
