A Quote by J.J. Sylvester on laws, purity, and theory

[on graph theory...] The theory of ramification is one of pure colligation, for it takes no account of magnitude or position; geometrical lines are used, but these have no more real bearing on the matter than those employed in genealogical tables have in explaining the laws of procreation.

J.J. Sylvester (1814 - 1897)
