Every man's world picture is and always remains a construct of his mind and cannot be proved to have any other existence.

If you cannot - in the long run - tell everyone what you have been doing, your doing has been worthless.

I insist upon the view that 'all is waves'.

Science cannot tell us a word about why music delights us, of why and how an old song can move us to tears.

I am very astonished that the scientific picture of the real world around me is deficient. It gives a lot of factual information, puts all our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity.
