We'll lose more species of plants and animals between 2000 and 2065 than we've lost in the last 65 million years. If we don't find answers to these problems, we're gonna be victims of this extinction event that we're at fault for.

I haven't eaten an animal in over twenty years!

Safety is really a concern of mine, and what I've been telling people recently is that until there's animal and human data on a drug it should probably be looked at very carefully.

In our own time, through integrative sciences like ecology and animal behavior and psychology we have re-understood what was forgotten during the reduction centuries of modern science. We've re-understood that the world is one thing, and it's a living thing. It's a thing with an intent and a spirit within it, and this is the key concept.

At still higher doses psilocybin triggers this activity in the language-forming capacity of the brain that manifests as song and vision. Psilocybin may have synergized the emergence of higher forms of psychic organization out of primitive protohuman animals. It can be seen as a kind of evolutionary enzyme, or evolutionary catalyst.

History, call it 15,000 or 25,000 years of duration, is the story of an animal, some kind of complex animal, becoming conscious.

All the accoutrements that distinguish us from animal existence were put in place when we had a different kind of mind than we have now. We didn't have a mind that favored role specialization, and male dominance, and anxiety over female sexual activity related to feelings of male ownership. That all came later.

What they [psychedelics] cause is what I'm advocating, a fundamental revaluation of cultural values, because culture as we're practicing it currently is causing a lot of pain to a lot of people, and animals, and ecosystems, none of whom were ever allowed to vote on whether they wanted this process to go in this direction.

For me, the glory of the human animal is cognitive activity.

We are like coral animals in a vast reef of excreted technological material that is wired for solid state data transfer.

We are like coral animals embedded in a technological reef of extruded psychic objects...All our tool-making implies our belief in an ultimate tool.

Since the very beginning of culture, what we seem to be are animals which take in raw material and excrete it imprinted with ideas.

Nothing heightens chaos more than a berserk wild animal right in the middle.

The same polarity of the male and female principle exists in nature; not only, as is obvious in animals and plants, but in the polarity of the two fundamental functions, that of receiving and penetrating. It is the polarity of earth and rain, of the river and the ocean, of night and day, of darkness and light, of matter and spirit.

Reason is man's instrument for arriving at the truth, intelligence is man's instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

Man may be defined as the animal that can say ''I,'' that can be aware of himself as a separate entity.

Man is the only animal that can be bored.

Even if man's hunger and thirst and his sexual strivings are completely satisfied, 'he' is not satisfied. In contrast to the animal his most compelling problems are not solved then, they only begin. He strives for power or for love, or for destruction, he risks his life for religious, for political, for humanistic ideals, and these strivings are what constitutes and characterizes the peculiarity of human life.

Reason is man's faculty for grasping the world by thought, in contradiction to intelligence, which is man's ability to manipulate the world with the help of thought. Reason is man's instrument for arriving at the truth, intelligence is man's instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

What is it that distinguishes man from animals? It is not his upright posture.

Man is the only animal who does not feel at home in nature, who can feel evicted from paradise, the only animal for whom his own existence is a problem that he has to solve and from which he cannot escape. He cannot go back to the prehuman state of harmony with nature, and he does not know where he will arrive if he goes forward. Man's existential contradiction results in a state of constant disequilibrium. This disequilibrium distinguishes him from the animal, which lives, as it were, in harmony with nature.

Man is the only animal for whom his own existence is a problem which he has to solve.

We're so much more likely to feel sympathy for an animal than another person; thus, the best fiction uses animals to define truly humane behavior.

So if animals aren't our friends, then what are they? The answer can be summed up between two buns.
