And the pursuit whose quest is Nature's understanding, has this among its rewards, that as it progresses its truth is testable. Truth is a 'value'. T… - Charles Scott Sherrington

Biology cannot go far in its subject before being met by mind.

The influence of mind on the doings of life makes mind an effective contribution to life. We can seize then how mind counts and has counted. That it has been evolved seems to assure us that it has counted. How it has counted would seem to be that the finite mind has influenced its individual's 'doing'. Lloyd Morgan, the biologist, urged that, 'the primary aim, object, and purpose of consciousness is control'. Dame Nature seems to have taken the like view.

Today Nature looms larger than ever and includes more fully than ever ourselves. It is, if you will, a machine, but it is a partly mentalized machine, and in virtue of including ourselves it is a machine with human qualities of mind. It is a running stream of energy—mental and physical—and unlike man-made machines it is actuated by emotions, fears and hopes, dislikes and love. It bids fair to be master of this our planet—'it looks before and after'. To what or to whom does it owe this eminent and seemingly unique status? It answers unhesitatingly that it owes it to itself. But to the semi-divine assembly which looks on, that answer would be impertinent but for its saving ignorance. We may suppose that if they hear it the stars smile. Human thought is left wondering. What is it all for? Man is too small and too perishable to be the object of this whole. A counsel is 'let us endure and be quiet'—a counsel which is the easier to follow because it seems all that there is for us to do, at least at the present moment.
