Somebody was saying to Picasso that he ought to make pictures of things the way they are-objective pictures. He mumbled that he wasn't quite sure what that would be.

A major difficulty is that the answer to the Riddle of the Sphinx is partly a product of the answers that we already have given to the riddle in its various forms.

Numbers are the product of counting. Quantities are the product of measurement. This means that numbers can conceivably be accurate because there is a discontinuity between each integer and the next. Between two and three there is a jump. In the case of quantity, there is no such jump; and because jump is missing in the world of quantity, it is impossible for any quantity to be exact. You can have exactly three tomatoes. You can never have exactly three gallons of water. Always quantity is approximate.

We are discovering today that several of the premises which are deeply ingrained in our way of life are simply untrue and become pathogenic when implemented with modern technology.
