“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.”

“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.”

Dieu existe? Oui http://books.google.com.mx/books/about/Dieu_existe_Oui.html?id=TBUCHQAACAAJ&redir_esc=y (1979). Paris. Stock. Christian Chabanis, p. 94. <br class="br">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 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.”

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

“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.”
