Looking not to any one time, but to all time, if my theory be true, numberless intermediate varieties, linking most closely all the species of the same group together, must assuredly have existed; but the very process of natural selection constantly tends, as has been so often remarked, to exterminate the parent forms and the intermediate links. Consequently evidence of their former existence could be found only amongst fossil remains.

Aristotle found support for his thesis in facts drawn from geopolitics or ‘natural law'. Greek superiority had to be proved demonstrably innate, a gift of nature. In one celebrated fragment he counsels Alexander to be ‘a hegemon [leader] of Greeks and a despot to the barbarians, to look after the former as after friends and relatives, and to deal with the latter as with beasts or plants'.

That intermediate manifestation of the divine process which we call the DNA code has spent the last 2 billion years making this planet a Garden of Eden. An intricate web has been woven, a delicate fabric of chemical-electrical-seed-tissue=organism=species. A dancing, joyous harmony of energy transactions is rooted in the 12 inches of topsoil which covers the rock
metal

core of this planet.

I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.
G. H. Hardy
Very little comes easily to our poor, benighted species (the first creature, after all, to experiment with the novel evolutionary inventions of self-conscious philosophy and art). Even the most "obvious,” "accurate,” and "natural” style of thinking or drawing must be regulated by history and won by struggle. Solutions must therefore arise within a social context and record the complex interactions of mind and environment that define the possibility of human improvement.

Ruskin's much-derided moral theory of art was part of an attempt to show that this human activity, which we value so highly, engaged the whole of human personality. His insistence on the sanctity of nature was part of an attempt to develop Goethe's intuition that form cannot be put together in the mind by an additive process, but is to be deduced from the laws of growth in living organisms, and their resistance to the elements.
