Pathology is a relatively easy thing to discuss, health is very difficult. This, of course, is one of the reasons why there is such a thing as the sacred, and why the sacred is difficult to talk about, because the sacred is peculiarly related to the healthy. One does not like to disturb the sacred, for in general, to talk about something changes it, and perhaps will turn it into a pathology.

There are times when I catch myself believing that there is such a thing as something; which is separate from something else.

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.

No organism can afford to be conscious of matters with which it could deal at unconscious levels.

After mastery comes artistry and not before.

Still more astonishing is that world of rigorous fantasy which we call mathematics.

It is of first-class importance that our answer to the Riddle of the Sphinx should be in step with how we conduct our civilisation, and this should in turn be in step with the actual workings of living systems.
