“There is no difference between the worry of a human mother and an animal mother for their offspring. A mother’s love does not derive from the intellect but from the emotions, in animals just as in humans.”

It should not be believed that all beings exist for the sake of the existence of man. On the contrary, all the other beings too have been intended for their own sakes and not for the sake of anything else.

For that which is without a beginning, a final cause need not be sought.

For it is said, You shall strengthen the stranger and the dweller in your midst and live with him, that is to say, strengthen him until he needs no longer fall upon the mercy of the community or be in need.

Astrology is a disease, not a science. It is a tree under the shadow of which all sorts of superstitions thrive. Only fools and charlatans lend value to it.

Every man should view himself as equally balanced: half good and half evil. Likewise, he should see the entire world as half good and half evil. With a single good deed he will tip the scales for himself, and for the entire world, to the side of good.

A truth does not become greater by repetition.

The knowledge of God, the formation of ideas, the mastery of desire and passion, the distinction between that which is to be chosen and that which is to be rejected, all these man owes to his form.

Nobody is ever impoverished through the giving of charity.

Consequently he who wishes to attain to human perfection, must therefore first study Logic, next the various branches of Mathematics in their proper order, then Physics, and lastly Metaphysics.

There are eight rungs in charity. The highest is when you help a man to help himself.

Astrology is a sickness, not a science. It is a tree under the shade of which all sorts of superstitions thrive.

In the realm of Nature there is nothing purposeless, trivial, or unnecessary.

Hear the truth from whomever says it.

The best part is coming. What’s the best part? You swallowing an entire cow whole? No. That’s the finale.

Usually, I’m only sad when something sad happens. I am not a melancholic person. I like to live very much in the present. If I was an animal, I’d be a little cat. They like to live life.

I stayed in show business to pay for my animal business.

I’m in the middle of my sixth book, which is about animals at the Los Angeles Zoo.

There is no more reason to believe that man descended from an inferior animal than there is to believe that a stately mansion has descended from a small cottage.

You know what the problem that animal activists sometimes have? They only concentrate on the heartbreaking things to the point where the general public thinks, ‘Oh, here comes those animal folks again and I’m going to hear all the things I don’t want to hear.’

Animals don’t lie. Animals don’t criticize. If animals have moody days, they handle them better than humans do.

I secretly want to be a zebra. That is why I always wear stripes.
