“What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question.”

“If the human species is differentiated from the beasts by the marvel of consciousness, then we enact our humanity and the very authenticity of our being by straining to "know" through awareness the "unthinkable" experience of others.”

“Among the earliest forms of human self-awareness was the awareness of being meat.”

“Most of us assume that human beings have free will. However, . . . [we] are very much conditioned by our species, culture, family, and by the past in general. . . . It is rare for a human being to have free will. . . . (140)”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”

“The self-aggrandizing and widespread assumption that we humans have the full complement of all of the emotions possible to all animals on Earth–basically, that all the marbles belong to us–is not only unscientific but also childish. Do we know how it feel is sail on an updraft in the sky, to echolocate our dinner in the dark, or to see at lightning speed with a compound eye? Fortunately, human understanding is maturing, and we are learning that animals are emotional, thinking, and self-aware beings relative to the niche that they were born to occupy.”
