Science is Built of Facts

Science is built up of facts, as a house is built of stones; but an accumulation of facts is no more a science than a heap of stones is a house.

Between the elements of a continuum there is a sort of intimate bond which makes a whole of them, in which the point is not prior to the line, but the line to the point.

Poincaré said so; and lines are not made of points in the way that counting numbers bigger than one are made of ones, although the number of all the points in a line will be made of ones in a similar way.
