It may be said that man can make or draw a triangle, and therefore a triangle is a human invention. But the triangle, when drawn, is no other than the image of the principle; it is a delineation to the eye, and from thence to the mind, of a principle that would otherwise be imperceptible. The triangle does not make the principle, any more than a candle taken into a room that was dark makes the chairs and tables that before were invisible. All the properties of a triangle exist independently of the figure, and existed before any triangle was drawn or thought of by man.
