“Darwin's statements concerning hybrids of the genera”

— Gregor Mendel

Letter VIII, July 3rd, 1870.
Here Mendel alludes to the now-discredit ideas of blending inheritance and pangenesis
Letters to Carl Nägeli
Context: Of the experiments of previous years, those dealing with Matthiola annua and glabra, Zea, and Mirabilis were concluded last year. Their hybrids behave exactly like those of Pisum. Darwin's statements concerning hybrids of the genera mentioned in The variation of animals and plants under domestication, based on reports of others, need to be corrected in many respects.

“The point of Darwin's statement is clear: in competitions among groups, those whose members have learned how to cooperate—that is, not to compete with one another—often win. Think of team sports. Darwin spoke of tribes as groups that would benefit from having a preponderance of cooperative members. The same reasoning applies to firms, neighborhoods, ethnic groups, and nations.”

“Even a statement very close to the periphery can be held true in the face of recalcitrant experience by pleading hallucination or by amending certain statements of the kind called logical laws. Conversely, by the same token, no statement is immune to revision. Revision even of the logical law of the excluded middle has been proposed as a means of simplifying quantum mechanics; and what difference is there in principle between such a shift and the shift whereby Kepler superseded Ptolemy, or Einstein Newton, or Darwin Aristotle?”

“Physiologic facts concerning the origin of species in nature were unknown in the time of Darwin... The experience of the breeders was quite inadequate to the use which Darwin made of it. It was neither scientific, nor critically accurate. Laws of variation were barely conjectured; the different types of variability were only imperfectly distinguished. The breeders' conception was fairly sufficient for practical purposes, but science needed a clear understanding of the factors in the general process of variation. Repeatedly Darwin tried to formulate these causes, but the evidence available did not meet his requirements.
Quetelet's law of variation had not yet been published. Mendel's claim of hereditary units for the explanation of certain laws of hybrids discovered by him, was not yet made. The clear distinction between spontaneous and sudden changes, as compared with the ever-present fluctuating variations, is only of late coming into recognition by agriculturists. Innumerable minor points which go to elucidate the breeders' experience, and with which we are now quite familiar, were unknown in Darwin's time. No wonder that he made mistakes, and laid stress on modes of descent, which have since been proved to be of minor importance or even of doubtful validity.”

“[L]et us consider, with respect to causes, what they are, and how many there are in number… this also must be done by us in discoursing concerning generation and corruption, and all physical mutation… knowing the principles of these…
Cause… is after one manner said to be that, from which, being inherent, something is produced… But after another manner cause is form and paradigm (and this is the definition of the essence of a thing) and the genera of this. …But it happens… that there are also many causes of the same thing, and this is not from accident. …seed, a physician, he who consults, and, in short, he who makes, are all of them causes, as that whence the principle of mutation, or permanency, or motion is derived. …It is, however, necessary always to investigate the supreme cause of every thing …Further still, it is necessary to investigate the genera of genera; and the particulars of particulars… We should also explore the capacities of the capabilities, and the energizers of the things affected by energy.”
