In everything, almost in everything, I wrote I was guided by the need of collecting ideas which, linked together, would be the expression of myself, though each individual idea, expressed separately in words, loses its meaning, is horribly debased when only one of the links, of which it forms a part, is taken by itself. But the interlinking of these ideas is not, I think, an intellectual process, but something else, and it is impossible to express the source of this interlinking directly in words; it can only be done indirectly by describing images, actions, and situations in words.
