"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."

"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."

"In the transmission of human culture, people always attempt to replicate, to pass on to the next generation the skills and values of the parents, but the attempt always fails because cultural transmission is geared to learning, not DNA."

"It is impossible, in principle, to explain any pattern by invoking a single quantity."

"It is to the Riddle of the Sphinx that I have devoted fifty years of professional life as an anthropologist."

"Science, like art, religion, commerce, warfare, and even sleep, is based on presuppositions."

"Rather, for all objects and experiences, there is a quantity that has optimum value. Above that quantity, the variable becomes toxic. To fall below that value is to be deprived."

"There is a strong tendency in explanatory prose to invoke quantities of tension, energy, and whatnot to explain the genesis of pattern. I believe that all such explanations are inappropriate or wrong."

"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."

"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."

"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?"

"It is, I claim, nonsense to say that it does not matter which individual man acted as the nucleus for the change. It is precisely this that makes history unpredictable into the future."

"Logic is a poor model of cause and effect."

"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."

"We do not know enough about how the present will lead into the future."

"If we pursue this matter further, we shall be told that the stable object is unchanging under the impact or stress of some particular external or internal variable or, perhaps, that it resists the passage of time."

"All experience is subjective."

"Money is always transitively valued. More money is supposedly always better than less money."

"Number is different from quantity."

"Every move we make in fear of the next war in fact hastens it."

"Logic can often be reversed, but the effect does not precede the cause."

"Language commonly stresses only one side of any interaction."

"To think straight, it is advisable to expect all qualities and attributes, adjectives, and so on to refer to at least two sets of interactions in time."

"Members of weakly religious families get, of course, no religious training from any source outside the family."
