ENDS AND MEANS gious teaching. Hamlet contains no abstract reasoning concerning quantity or number and no experimental reason concerning evidence; nor does the Hammerklavier Sonata, nor Donatello's David, nor the Tao Te Chingy nor The Folio-wing of Christ. Commit them therefore to the flames: for they can contain-nothing but sophistry and illusion. We are living how, not in the delicious intoxication induced by the early successes of science, but in a rather grisly morning-after, when it has become apparent that what triumphant science has done hitherto is to improve the means for achieving unimproved or actually deteriorated ends. In this condition of apprehensive sobriety we are able to see that the contents of literature, art, music—even in some measure of divinity and school metaphysics—are not sophistry and illusion, but simply those elements of experience which scientists chose to leave out of account, for the good reason that they had no intellectual methods for dealing with them. In the arts, in philosophy, in reli- gion men are trying—doubtless, without complete success —to describe and explain the non-measurable, purely quali- tative aspects of reality. Since the time of Galileo, scientists have admitted, sometimes explicitly, but much more often by implication, that they are incompetent to discuss such matters. The scientific picture of the world is what it is because men of science combine this incompetence with certain special competences. They have no right to claim that this product of incompetence and specialization is a complete picture of reality. As a matter of historical fact, however,, this claim has constantly been made. The suc- cessive steps in the process of identifying an arbitrary abstraction from reality with reality itself have been described, very fully and lucidly, in Burtt's excellent Metaphysical Foundations of Modern Science; and it is therefore unnecessary .for me to develop the theme any further. All that I need add is the fact that, in recent years, 268
