“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

Context: Life, faculties, production — in other words, individuality, liberty, property — this is man. And in spite of the cunning of artful political leaders, these three gifts from God precede all human legislation, and are superior to it. Life, liberty, and property do not exist because men have made laws. On the contrary, it was the fact that life, liberty, and property existed beforehand that caused men to make laws in the first place.

The Dominant Idea (1910)
Context: It is not to be supposed that any one will attain to the full realization of what he purposes, even when those purposes do not involve united action with others; he will fall short; he will in some measure be overcome by contending or inert opposition. But something he will attain, if he continues to aim high.
What, then, would I have? you ask. I would have men invest themselves with the dignity of an aim higher than the chase for wealth; choose a thing to do in life outside of the making of things, and keep it in mind, — not for a day, nor a year, but for a life-time. And then keep faith with themselves! Not be a light-o'-love, to-day professing this and to-morrow that, and easily reading oneself out of both whenever it becomes convenient; not advocating a thing to-day and to-morrow kissing its enemies' sleeve, with that weak, coward cry in the mouth, "Circumstances make me." Take a good look into yourself, and if you love Things and the power and the plenitude of Things better than you love your own dignity, human dignity, Oh, say so, say so! Say it to yourself, and abide by it. But do not blow hot and cold in one breath. Do not try to be a social reformer and a respected possessor of Things at the same time. Do not preach the straight and narrow way while going joyously upon the wide one. Preach the wide one, or do not preach at all; but do not fool yourself by saying you would like to help usher in a free society, but you cannot sacrifice an armchair for it.
