Man is the only animal that deals in that atorcity of atrocities, War. He is the only one that gathers his brethren about him and goes forth in cold blood and calm pulse to exterminate his kind.
Everything which distinguishes man from the animals depends upon this ability to volatilize perceptual metaphors in a schema, and thus to dissolve an image into a concept.
Often and often afterwards, the beloved Aunt would ask me why I had never told anyone how I was being treated. Children tell little more than animals, for what comes to them they accept as eternally established.
I can no more explain why I like "natural history" than why I like California canned peaches; nor why I do not care for that enormous brand of natural history which deals with invertebrates any more than why I do not care for brandied peaches. All I can say is that almost as soon as I began to read at all I began to like to read about the natural history of beasts and birds and the more formidable or interesting reptiles and fishes.
The fly ought to be used as the symbol of impertinence and audacity; for whilst all other animals shun man more than anything else, and run away even before he comes near them, the fly lights upon his very nose.
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.
There are three things that are the motives of choice and three that are the motives of avoidance; namely, the noble, the expedient, and the pleasant, and their opposites, the base, the harmful, and the painful. Now in respect of all these the good man is likely to go right and the bad to go wrong, but especially in respect of pleasure; for pleasure is common to man with the lower animals, and also it is a concomitant of all the objects of choice, since both the noble and the expedient appear to us pleasant.
The knowledge of the soul admittedly contributes greatly to the advance of truth in general, and, above all, to our understanding of Nature, for the soul is in some sense the principle of animal life.
It is necessary to correct the error that vegetarianism has made us weak in mind, or passive or inert in action. I do not regard flesh-food as necessary at any stage
Nature has willed that man should, by himself, produce everything that goes beyond the mechanical ordering of his animal existence, and that he should partake of no other happiness or perfection than that which he himself, independently of instinct, has created by his own reason.
The aim of education is to make the pupil like and dislike what he ought....The little human animal will not at first have the right responses. It must be trained to feel pleasure, liking, disgust, and hatred at those things which really are pleasant, likable, disgusting, and hateful.
In a civilized and cultivated country wild animals only continue to exist at all when preserved by sportsmen. the excellent people who protest against all hunting, and consider sportsmen as enemies of wild life, are ignorant of the fact that in reality the genuine sportsman is by all odds the most important factor in keeping the larger and more valuable wild creatures from total extermination.
If it's a question about stuff that matters to you personally, like favorite food, favorite piece of knowledge, favorite animal, it's hard not to have an opinion and want to quantify things.
