A Quote by Asa Gray

But it was soon ascertained that this quaternary matter of the animal body was chemically the same in the plant, was elaborated there, and only appropriated by the animal.
You could think of an ecosystem as a bunch of antagonistic arms races, almost: Everything that an animal depends upon for food is the body part of some other animal or plant who would just as soon keep that body part for itself.
Man is a thinking animal, a talking animal, a toolmaking animal, a building animal, a political animal, a fantasizing animal. But, in the twilight of a civilization he is chiefly a taxpaying animal.
Lectins are plant proteins that protect the plant and its seeds from being eaten by basically hacking into the animal's immune system, causing the animal to have inflammation.
I'm not into animal rights. I'm only into animal welfare and health. I've been with the Morris Animal Foundation since the '70s. We're a health organization. We fund campaign health studies for dogs, cats, lizards and wildlife. I've worked with the L.A. Zoo for about the same length of time. I get my animal fixes!
He said that man’s heart was the only bad heart in the animal kingdom; that man was the only animal capable of feeling malice, envy, vindictiveness, revengefulness, hatred, selfishness, the only animal that loves drunkenness, almost the only animal that could endure personal uncleanliness and a filthy habitation, the sole animal in whom was fully developed the base instinct called patriotism, the sole animal that robs, persecutes, oppresses and kills members of his own tribe, the sole animal that steals and enslaves the members of any tribe.
Not only are the philosophies of animal rights and animal welfare separated by irreconcilable differences... the enactment of animal welfare measures actually impedes the achievement of animal rights... Welfare reforms, by their very nature, can only serve to retard the pace at which animal rights goals are achieved.
I fear animals regard man as a creature of their own kind which has in a highly dangerous fashion lost its healthy animal reason - as the mad animal, as the laughing animal, as the weeping animal, as the unhappy animal.
There are various causes for the generation of force: a tensed spring, an air current, a falling mass of water, fire burning under a boiler, a metal that dissolves in an acid-one and the same effect can be produced by means of all these various causes. But in the animal body we recognise only one cause as the ultimate cause of all generation of force, and that is the reciprocal interaction exerted on one another by the constituents of the food and the oxygen of the air. The only known and ultimate cause of the vital activity in the animal as well as in the plant is a chemical process.
I died as a mineral and became a plant, I died as a plant and rose to animal, I died as an animal and I was Man. Why should I fear? When was I less by dying?
Not only does every animal live at the expense of some other animal or plant, but the very plants are at war.... The individuals of a species are like the crew of a foundered ship, and none but good swimmers have a chance of reaching the land.
You can go from object to object, from plant to plant, from animal to animal and regard them as symbols for the spiritual. In this way, you make your imaginative capacities fluid and release them from the sharp contours of sense perception.
A lot of animal experiments consider only commercial interests. We want to ban all animal experiments as soon as possible.
As humans, we do get to choose what we eat, and when we choose to eat a plant, we are eating (i.e., harming) just that plant, plus indirectly whatever nutrients that plant consumed over its lifetime (and we are also harming whatever beings may have been living on that plant or who were injured or killed in the harvesting process). But when we eat an animal, we are eating not just that animal, but also indirectly all of the plants and other beings that that animal ate over its lifetime - those plants became the flesh that we eat.
The human being is in the most literal sense a political animal, not merely a gregarious animal, but an animal which can individuate itself only in the midst of society.
Next it was found that it was physiologically and structurally the same in the plant, that it was the living part of the plant, that which manifested the life and did the work in vegetable as well as in animal organisms.
There cannot be an animal body without a territorial body: three bodies are grafted over each other: the territorial body - the planet, the social body - the couple, and the animal body - you and me. And technology splits this unity, leaving us without a sense of where we are. This, too, is de-realization.
