The idea persists, none the less, that there might be no order at all , and that the mathematical order of things, being a conquest over disorder, possesses a positive reality. In examining this point, we shall see what a prominent part the idea of disorder plays in problems relative to the theory of knowledge. It does not appear explicitly, and that is why it escapes our attention. It is, however, with the criticism of this idea that a theory of knowledge ought to begin, for if the great problem is to know why and how reality submits itself to an order, it is because the absence of every kind of order appears possible or conceivable. The idea of disorder, in the sense of absence of order, is then what must be analyzed first.
Philosophy borrows it from daily life.
And it is unquestionable that, when ordinarily we speak of disorder, we are thinking of something. Bergson restarts his footnote counts on each page. So to refer a footnote, one must state page number and footnote number. Difficulties and illusions are generally due to this, that we accept as final a manner of expression essentially provisional. They are due to our bringing into the domain of speculation a procedure made for practice.
