For the real difference between humans and other animals is that humans alone have perception of good and evil, just and unjust, etc. It is the sharing of a common view in these matters that makes a household and a state.
There is no character, howsoever good and fine, but it can be destroyed by ridicule, howsoever poor and witless. Observe the ass, for instance: his character is about perfect, he is the choicest spirit among all the humbler animals, yet see what ridicule has brought him to. Instead of feeling complimented when we are called an ass, we are left in doubt.
"It is essential to understand this point thoroughly: that the thing-in-itself, whether animal, vegetable, or mineral, is not only unknowable-it does not exist. This is important not only for sanity and peace of mind, but also for the most "practical" reasons of economics, politics, and technology.. This is not to say only that things exist in relation to one another, but that what we call "things" are no more than glimpses of a unified process. Certainly, this process has distinct features which catch our attention, but we must remember that distinction is not separation."
Once you begin to take yourself seriously as a leader or as a follower, as a modern or as a conservative, then you become a self-conscious, biting, and scratching little animal whose work is not of the slightest value or importance to anybody.
Three quiet days. This hell fiend is like a cat with a mouse. She lets me loose only to pounce upon me again. I am never so frightened as when every thing is still.
Hippogriff, n. An animal (now extinct) which was half horse and half griffin. The griffin was itself a compound creature, half lion and half eagle. The hippogriff was actually, therefore, only one-quarter eagle, which is two dollars and fifty cents in gold. The study of zoology is full of surprises.
A healthy-minded boy should feel hearty contempt for the coward and even more hearty indignation for the boy who bullies girls or small boys, or tortures animals.
Let's stick to the practical and the concrete: Would you like it if people lived in a virtual world? If machines were smarter than people? If, in the future, people, animals and plants were products of technology? If you don't like these ideas, then for you the computer and biological sciences clearly are dangerous.
The similarities among animals that are on the surface very different are no coincidence. In fact, animal locomotion is no different than other flows, animate and inanimate they all develop in space and in time such that they optimize the flow of material.
Man is by nature a social animal; an individual who is unsocial naturally and not accidentally is either beneath our notice or more than human. Society is something that precedes the individual. Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god.
Indecency, vulgarity, obscenity - these are strictly confined to man; he invented them. Among the higher animals there is no trace of them. They hide nothing. They are not ashamed.
