We require just a little order to protect us from the chaos. Nothing is more distressing than a thought that escapes itself, than ideas that fly off, that disappear hardly formed, already eroded by forgetfulness or precipitated into others that we no longer master. These are infinite variabilities, the appearing and disappearing of which coincide. They are infinite speeds that blend into the immobility of the colourless and silent nothingness they traverse, without nature or thought. This is the instant of which we do not know whether it is too long or too short for time. We receive sudden jolts that beat like arteries. We constantly lose our ideas. That is why we want to hang on to fixed opinions so much. We ask only that our ideas are linked together according to a minimum of constant rules. All that the association of ideas has ever meant is providing us with these protective rules – resemblance, contiguity, causality – which enable us to put some order into ideas, preventing our “fantasy” (delirium, madness) from crossing the universe in an instant, producing winged horses and dragons breathing fire.
