The mode of being of life, and even that which determines the fact that life cannot exist without prescribing its forms for me, are given to me, fundamentally, by my body; the mode of being of production, the weight of its determinations upon my existence, are given to me by my desire; and the mode of being of language, the whole backwash of history to which words lend their glow at the instant they are pronounced, and perhaps even in a time more imperceptible still, are given to me only along the slender chain of my speaking thought.
