“It is conceivable that animal life might have the attribute of using the heat of surrounding matter, at its natural temperature, as a source of energy for mechanical effect.... The influence of animal or vegetable life on matter is infinitely beyond the range of any scientific enquiry hitherto entered on. Its power of directing the motions of moving particles, in the demonstrated daily miracle of our human free-will, and in the growth of generation after generation of plants from a single seed, are infinitely different from any possible result of the fortuitous concurrence of atoms.”

As quoted in The Life of Lord Kelvin (1910), by Silvanus Phillips, Volume 2, (2005 edition, . p. 1093)

“It is impossible by means of inanimate material agency, to derive mechanical effect from any portion of matter by cooling it below the temperature of the coldest of the surrounding objects. [Footnote: ] If this axiom be denied for all temperatures, it would have to be admitted that a self-acting machine might be set to work and produce mechanical effect by cooling the sea or earth, with no limit but the total loss of heat from the earth and sea, or in reality, from the whole material world.”

“One might almost say that the plant is the framework, the foundation of the animal, and that to form the animal it sufficed to cover this foundation with a system of organs fitted to establish relations consists forms with the world outside. It follows of the succession substance of the animal form two quite distinct classes. One class in a continual into its own assimilation molecules that the functions and of excretion; through these functions the animal incessantly transsurrounding bodies, later to reject these molecules when they have become heterogeneous to it. Through this first class of functions the animal exists only within itself; through the other class it exists outside; it is an inhabitant of the world, and not, like the plant, of the place which saw its birth. The animal feels and perceives its surroundings, reflects its sensations, moves of its own will under their influence, and, as a rule, can communicate by its voice its desires and its fears, its pleasures or its pains. I call organic life the sum of the functions of the former class, for all organised creatures, plants or animals, possess them to a more or less marked degree, and organised structure is the sole condition necessary to their exercise. The combined functions of the second class form the ' animal' life named because it is the exclusive attribute of the animal kingdom.”

Marie François Xavier Bichat (1771–1802) French anatomist and physiologist

Original: (fr) On dirait que le végétal est l'ébauche, le canevas de l'animal, et que, pour former ce dernier, il n'a fallu que revêtir ce canevas d'un appareil d'organes extérieurs, propres à établir des relations. Il résulte de là que les fonctions de l'animal forment deux classes très-distinctes. Les unes se composent d'une succession habituelle d'assimilation et d'excrétion ; par elles il transforme sans cesse en sa propre substance les molécules des corps voisins, et rejette ensuite ces molécules, lorsqu'elles lui sont devenues hétérogènes. Il ne vit qu'en lui, par cette classe de fonctions ; par l'autre il existe hors de lui : il est l'habitant du monde, et non, comme le végétal, du lieu qui le vit naître. Il sent et aperçoit ce qui l'entoure, réfléchit ses sensations, se meut volontairement d'après leur influenc, et le plus souvent peut communiquer par la voix, ses désirs et ses craintes, ses plaisirs ou ses peines. J'appelle vie organique l'ensemble des fonctions de la première classe, parce que tous les êtres organisés, végétaux ou animaux, en jouissent à un degré plus ou moins marqué, et que la texture organique est la seule condition nécessaire à son exercice. Les fonctions réunies de la seconde classe forment la vie animale, ainsi nommée, parce qu'elle est l'attribut exclusif du règne animal.

“I answer that, It was necessary for woman to be made, as the Scripture says, as a "helper" to man; not, indeed, as a helpmate in other works, as some say, since man can be more efficiently helped by another man in other works; but as a helper in the work of generation. This can be made clear if we observe the mode of generation carried out in various living things. Some living things do not possess in themselves the power of generation, but are generated by some other specific agent, such as some plants and animals by the influence of the heavenly bodies, from some fitting matter and not from seed: others possess the active and passive generative power together; as we see in plants which are generated from seed; for the noblest vital function in plants is generation. Wherefore we observe that in these the active power of generation invariably accompanies the passive power. Among perfect animals the active power of generation belongs to the male sex, and the passive power to the female. And as among animals there is a vital operation nobler than generation, to which their life is principally directed; therefore the male sex is not found in continual union with the female in perfect animals, but only at the time of coition; so that we may consider that by this means the male and female are one, as in plants they are always united; although in some cases one of them preponderates, and in some the other. But man is yet further ordered to a still nobler vital action, and that is intellectual operation. Therefore there was greater reason for the distinction of these two forces in man; so that the female should be produced separately from the male; although they are carnally united for generation. Therefore directly after the formation of woman, it was said: "And they shall be two in one flesh"”
