Do you want an example? I will take that of human personality. The ego is one; the ego is many: no one contests this double formula. But everything admits of it; and what is its lesson to us? Observe what is bound to happen to the two concepts of unity and multiplicity, by the mere fact that we take them for general frames independent of the reality contained, for detached language admitting empty and blank definition, always representable by the same word, no matter what the circumstances: they are no longer living and coloured ideas, but abstract, motionless, and neutral forms, without shades or gradations, without distinction of case, characterising two points of view from which you can observe anything and everything. This being so, how could the application of these forms help us to grasp the original and peculiar nature of the unity and multiplicity of the ego? Still further, how could we, between two such entities, statically defined by their opposition, ever imagine a synthesis? Correctly speaking, the interesting question is not whether there is unity, multiplicity, combination, one with the other, but to see what sort of unity, multiplicity, or combination realises the case in point; above all, to understand how the living person is at once multiple unity and one multiplicity, how these two poles of conceptual dissociation are connected, how these two diverging branches of abstraction join at the roots. The interesting point, in a word, is not the two symbolical colourless marks indicating the two ends of the spectrum; it is the continuity between, with its changing wealth of colouring, and the double progress of shades which resolve it into red and violet. But it is impossible to arrive at this concrete transition unless we begin from direct intuition and descend to the analysing concepts.
