"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: "In microorganisms, the generation time is rather short and the size of the population can be enormous. Therefore, mutation acts as a very powerful evolutionary process during a shorter lapse of time than in populations of higher organisms"(Levine, 1969, p. 196. the italics are mine) 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."

"For those who would still doubt the relevance of our criticisms, another quote from a paper written by two American biologists, King and Jukes (1969), is presented: "Darwinism is so well established that it is difficult to think of evolution except in terms of selection for desirable characteristics and advantageous genes. New technical developments and new knowledge, such as the sequential analysis of proteins and the deciphering of the genetic code, have made a much closer examination of evolutionary processes the sequential analysis of proteins and the deciphering of the genetic code, have made a much closer examination of evolutionary processes possible, and therefore necessary.". These biologists are convinced that the Darwinian credo is correct, and they accept it. They are quite sincere but they are not critical enough. Biochemists and biologists who adhere blindly to the Darwinism theory search for results that will be in agreement with their theories and consequently orient their research in a given direction, whether it be in the field of ecology, ethology, sociology, demography (dynamics of populations), genetics (so-called evolutionary genetics), or paleontology. This intrusion of theories has unfortunate results: it deprives observations and experiments of their objectivity, makes them biased, and, moreover, creates false problems. Heedful of genetics and demography, Darwinians have seldom taken fossils* into consideration, or, and this is more serious, they have applied the laws of genetics to them without making a critical analysis; considering our ignorance of the relationships between fossils, which in most cases are found very far apart and in distinct beds, this approach can only be arbitrary."

"The Darwinians have coined the terms pseudoteleology and teleonomy to designate the finality which they at the same time deny. Appearances are deceptive, they say; the materials of life are always the work of chance. What some take for finality is only the result of the ordering of random materials bynatural selection. Even were this to be true, as it is not, the demon of finility would still not have been exorcized. For natural selection is, in essence and function, the supreme finilizing agent. Actually, the terms pseudoteleology and teleonomy are the homage paid to finality, as hypocrisy pays homage to virtue. Giard (1905), himself a shrewd scholar but blinded by a foolish anticlericalism, went so far as to abjure Lamarckism and write, "To account for the wondrous adaptations such as those we observe between orchids and the insects that fertilize them, we have hardly any choice but the bare alternative hypotheses: the intervention of a sovereignly intelligent being, and selection." He cannot have seriously subjected his supposed dilemma to critical scrutiny or he would have seen that he was substituting for the dethroned divinity just such another, a sorting and finalizing, in sum transcendental, agent, natural selection. Paul Wintrebert, a convinced and even intractable atheist, did not fall into the same trap but realized perfectly that Giard's alternative involves, whatever opinion be held, recognizing the intervention of a purposive guiding agent. Giard's concept, which is that held by many atheists and "freethinkers", gives a singular and belittling idea of God. The Almighty, obliged to remodel and retouch His own handiwork."

"[F]rom the earliest periods of time [man] alone has divided the empire of the world between him and Nature. ...[H]e rather enjoys than possesses, and it is by constant and perpetual activity and vigilance that he preserves his advantage, for if those are neglected every thing languishes, changes, and returns to the absolute dominion of Nature. She resumes her power, destroys the operations of man; envelopes with moss and dust his most pompous monuments, and in the progress of time entirely effaces them, leaving man to regret having lost by his negligence what his ancestors had acquired by their industry. Those periods in which man loses his empire, those ages in which every thing valuable perishes, commence with war and are completed by famine and depopulation. Although the strength of man depends solely upon the union of numbers, and his happiness is derived from peace, he is, nevertheless, so regardless of his own comforts as to take up arms and to fight, which are never-failing sources of ruin and misery. Incited by insatiable avarice, or blind ambition, which is still more insatiable, he becomes callous to the feelings of humanity; regardless of his own welfare, his whole thoughts turn upon the destruction of his own species, which he soon accomplishes. The days of blood and carnage over, and the intoxicating fumes of glory dispelled, he beholds, with a melancholy eye, the earth desolated, the arts buried, nations dispersed, an enfeebled people, the ruins of his own happiness, and the loss of his real power."

"Buffon produced in the fifty years from 1749 an Histoire Naturelle... one of the signal products of eighteenth-century science. ...He attempted to see nature as a whole, produced a vast synthesis and sought to give a picture of the history of the earth... [If] Newton had appeared to reduce the inanimate world to a system of law, Buffon... set his mind on a similar achievement, and even a wider one—comprising... biological phenomana and expanding into the realm of history. ...Along with Leibnitz he believed that the earth had once been in an incandescent state... part of the sun, but had broken away after a collision with a comet. He rejected the tradition that this globe was only six thousand years old and made an attempt to set out the periods or stages of its history; a time when mountain ranges were formed...a time when waters entirely covered... the globe... and a time when the continents came to be separated from one another. ...He held something like Leibnitz's idea that every plant and animal was composed of a mass of minute particles, each of which was a pattern of the whole individual; and this enabled him to explain the origin of living creatures without reference to an act of creation. He tried to show that no absolutely definite boundary existed between the animal and vegetable kingdoms. Nature always proceeds by nuances, he said."
