Evolution of living organisms: evidence for a new theory of transformation (1977)
Context: We have gone from Darwinism into neo-Darwinism, and, very recently, to ultra-Darwinism, which not only claims to be the sole custodian truth in regard to evolution, but to be evolution itself. Darwin himself did not display so much confidence when writing to one of his grandsons... Present-day ultra-Darwinism, which is so sure of itself, impresses incompletely informed biologists, misleads them, and inspires fallacious interpretations. The following is one of the numerous examples found in books today:
This text suggests that modern bacteria are evolving very quickly, thanks to their innumerable mutations. Now, this is not true. For millions, or even billions of years, bacteria have not transgressed the structural frame within which they have always fluctuated and still do.
It is a fact that microbiologists can see in their cultures species of bacteria oscillating around an intermediate form, but this does not mean that two phenomena, which are quite distinct, should be confused; the variation of the genetic code because of a DNA copy error and evolution. To vary and to evolve are two different things; this can never be sufficiently emphasized.
“If my view be correct, Erasmus Darwin planted the seed of suggestion in questioning whether adaptation meant no more to man than illustration of creative ingenuity; the one grandson, Charles Darwin, collected the facts which had to be dealt with and linked them together by wide-reaching hypotheses; the other grandson, Francis Galton, provided the methods by which they could be tested...”

Context: This century will be called Darwin’s century. He was one of the greatest men who ever touched this globe. He has explained more of the phenomena of life than all of the religious teachers. Write the name of Charles Darwin on the one hand and the name of every theologian who ever lived on the other, and from that name has come more light to the world than from all of those.

Letters to Carl Nägeli

He here refers to his proposal in "A unitary hypothesis of mind-brain interaction in the cerebral cortex" (1990); published in Proceedings of the Royal Society B 240, p. 433 - 451
How the Self Controls Its Brain (1994)
Context: The hypothesis has been proposed that all mental events and experiences, in fact the whole of the outer and inner sensory experiences, are a composite of elemental or unitary mental experiences at all levels of intensity. Each of these mental units is reciprocally linked in some unitary manner to a dendron … Appropriately we name these proposed mental units 'psychons.' Psychons are not perceptual paths to experiences. They are the experiences in all their diversity and uniqueness. There could be millions of psychons each linked uniquely to the millions of dendrons. It is hypothesized that it is the very nature of psychons to link together in providing a unified experience.
