Famous Pierre-Paul Grassé Quotes

“The study of contemporary species does not establish the existence of evolution; it provides facts which support it, but which do not fully demonstrate its existence. This is understandable, since at present we cannot show the series of successive stages which make up evolution, but only a fleeting picture of evolution.”

“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.”

“The philosopher considering the Universe in its entirety is led to admit that there is only one necessary, absolute being, God. All other beings are contingent; this is why Pascal said of himself: "I feel that I might not have been… therefore I am not a necessary being" (Pensées, No. 597). The proposition applies equally to every living thing.”

Evolution of living organisms: evidence for a new theory of transformation (1977)
Original: Le philosophe, considérant l'univers dans son intégralité, est conduit à n'admettre qu'un seul être nécessaire, absolu, Dieu. Tous les autres sont contingents; c'est pour cela que Pascal disait de lui-même : « Je sens que je puis n'avoir pas été... donc je ne suis pas un être nécessaire » (Pensées, 597). Cette proposition s'applique avec autant de justesse à tout être

“The immanent purpose is an intrinsic property of living beings, without it, they would not exist. Consider the autonomous function units and their components: organs, tissues, isolated cells, as well as other properties such as nutrition, body defense, growth, reproduction, to which they are subject at the end. When it comes to these properties, biologists do not argue; but if you pronounce the word purpose, there is a public outcry. Probably because they do not distinguish the purpose of fact or immanent, the trascendental purpose. Of the latter, the biologist has little or nothing to say; it is a matter of metaphysics.”

Grassé, Pierre Paul (1977); Evolution of living organisms: evidence for a new theory of transformation. Academic Press, p. 2
Evolution of living organisms: evidence for a new theory of transformation (1977)
Original: La finalité immanente est une propriété intrinseque des etres vivants, sans elle, ils n'existeraient pas. Considérés en tant qu' unités fonctionelles autonomes, leurs constituants: organes, tissus, cellule isolée, au meme titre que les autres propriétés: nutrition, défense de l'organisme, croissance, reproduction, sont subordonnés à une fin. Quand il s'agit de ces propriétes, les biologistes ne se disputent pas; mais si l'on pronounce le mot finalité, c'est un levée de boucliers. Probablement parce qu'ils ne distinguent pas la finalité de fait ou immanente, de la finalité trascendante. Sur cette derniere, le biologiste n'a que peu, sinon rien à dire; elle ressortit de la métaphysique

“When we consider a human work, we believe we know where the "intelligence" which fashioned it comes from; but when a living being is concerned, no one knows or ever knew, neither Darwin nor Epicurus, neither Leibniz nor Aristotle, neither Einstein nor Parmenides. An act of faith is necessary to make us adopt one hypothesis rather than another. Science, which does not accept any credo, or in any case should not, acknowledges its ignorance, its inability to solve this problem which, we are certain, exists and has reality.”

Pierre-Paul Grassé

Evolution of living organisms: evidence for a new theory of transformation (1977)

“Here we are, up to our ears in transcendence: Any organization or function is controlled by it. The building blocks for making living creatures are utilized by it. Thus, the entire world of living beings is transcended by phenomena that create finality. Natural selection working for the continuance and welfare of animals, plants, and man himself, is seen to be the grand law which organizes the living universe. So the Darwinians, who fancied they had exorcized finalism and transcendency but forgot to analyze critically the idea of natural selection, failed to see its implications or metaphysical consequences. They thought they were absolved from giving any finalization or deistic interpretation by decreeing that on earth all is but deceptive appearances; finality is a sham, guided evolution illusory. How is it possible to understand such an attitude?”

Pierre-Paul Grassé Quotes

“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,”

Pierre-Paul Grassé

Grassé, Pierre Paul (1977); Evolution of living organisms: evidence for a new theory of transformation. Academic Press, p. 7
Evolution of living organisms: evidence for a new theory of transformation (1977)
Context: 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:. 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.

“Through use and abuse of hidden postulates, of bold, often ill-founded extrapolations, a pseudoscience has been created. It is taking root in the very heart of biology and is leading astray many biochemists and biologists, who sincerely believe that the accuracy of fundamental concepts has been demonstrated, which is not the case.”

Context: Through use and abuse of hidden postulates, of bold, often ill-founded extrapolations, a pseudoscience has been created. It is taking root in the very heart of biology and is leading astray many biochemists and biologists, who sincerely believe that the accuracy of fundamental concepts has been demonstrated, which is not the case. Wishing to point out this type of misconception, we quote P. T. Mora, an American biochemist, who writes about polysaccharides contained in the cell membrane: To admit that the action of enzymes and, enzymes and, more important, that their foundation is directed by the genetic code should not permit one to mantain that the information was selected by evolution (the consequence is mistaken for the cause); no one knows anything about this.

“A given phenomenon, today considered random, may tomorrow be considered determined because its causes will have been unraveled by thorough and specific study.”

Pierre-Paul Grassé

Grassé, Pierre Paul (1977); Evolution of living organisms: evidence for a new theory of transformation. Academic Press, p. 279
Evolution of living organisms: evidence for a new theory of transformation (1977)
Context: Exceptional, unforeseeable, or even inexplicable phenomena would hence be fortuitous. these very vague adjectives too often have a merely circumstancial meaning. A given phenomenon, today considered random, may tomorrow be considered determined because its causes will have been unraveled by thorough and specific study.
Biologists, whose task is not to seek moral causes or intentions, must first of all make sure that so-called random facts really are random facts; they must constantly keep in mind Poincare's (1912b, p. 65) famous phrase: "Chance is only the measure of our ignorance."

“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.”

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.

“Natural order was not invented by the human mind or set up by certain perceptive powers… The existence of order presupposes the existence of organizing intelligence. Such intelligence can be none other than God's.”

Original: L’ordre naturel n’est pas une invention de l’esprit humain et une mise en place de certaines propriétés d’observation... Qui dit ordre dit intelligence organisatrice. Cette intelligence ne peut être que celle de Dieu.

“The mutation of bacteria and viruses are merely hereditary fluctuations around a median position; a swing to the right, a swing to the left, but no final evolutionary effect.”
