only the relations between things. Outside of these relations there is no knowable reality. - Henri Poincaré

Doubting everything and believing everything are two equally convenient solutions that guard us from having to think.

But these labels can only be finite in number. On that score, psychologic time should be discontinuous.

Let us try to represent the figure formed by these two curves and their intersections in infinite number, each corresponding to a doubly asymptotic solution, these intersections form a kind of mesh, of fabric, of infinitely tight network; each of the two curves must never intersect itself, but it must fold back on itself in a very complex way in order to cross an infinite number of times all the meshes of the network. On will be struck by the complexity of this figure, which I do not even try to draw. Nothing is more likely to give us an idea of the complexity of the three-body problem and in general of all the problems of dynamics where there is no uniform integral and where the Bohlin series are divergent.
