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.

Multiple descriptions are better than one.

Interesting phenomena occur when two or more rhythmic patterns are combined, and these phenomena illustrate very aptly the enrichment of information that occurs when one description is combined with another.

Science sometimes improves hypotheses and sometimes disproves them. But proof would be another matter and perhaps never occurs except in the realms of totally abstract tautology. We can sometimes say that if such and such abstract suppositions or postulates are given, then such and such abstract suppositions or postulates are given, then such and such must follow absolutely. But the truth about what can be perceived or arrived at by induction from perception is something else again.

Logic cannot model causal systems, and paradox is generated when time is ignored [as in logic].

But epistemology is always and inevitably personal. The point of the probe is always in the heart of the explorer: What is my answer to the question of the nature of knowing?

Official education was telling people almost nothing of the nature of all those things on the seashores, and in the redwood forests, in the deserts and in the plains.
