“We don’t let animals suffer, so why humans?”

The more you learn, the more you know. The more you know, the more you forget. The more you forget, the less you know. So why bother to learn.

Love the neighbour. But don’t get caught.

Nothing is better than reading and gaining more and more knowledge.

I think the human race doesn’t have a future if we don’t go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future.

I’m not afraid of death, but I’m in no hurry to die.

I’d say I don’t believe in God, but I’m afraid He might hear me.

There is a fundamental difference between religion, which is based on authority, and science, which is based on observation and reason. Science will win because it works.

There is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap.

Time travel may be possible, but it is not practical.

Science is not only a disciple of reason but, also, one of romance and passion.

It matters if you just don’t give up.

We are all now connected by the Internet, like neurons in a giant brain.

One can’t prove that God doesn’t exist. But science makes God unnecessary. The laws of physics can explain the universe without the need for a creator.

I have experimental evidence that time travel is not possible.

Science can explain the universe without the need for a Creator.

I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.

A wicked wife, a false friend, a saucy servant and living in a house with a serpent in it are nothing but death.

I’m human, you’re human. So they said, but inside we’re all animals.

Men, like animals, naturally multiply in proportion to the means of their subsistence.

Although an ass is tired, he continues to carry his burden; he is unmindful of cold and heat; and he is always contented; these three things should be learned from the ass.

The one excellent thing that can be learned from a lion is that whatever a man intends doing should be done by him with a whole-hearted and strenuous effort.

We should always speak what would please the man of whom we expect a favor, like the hunter who sings sweetly when he desires to shoot a deer.

Union in privacy (with one’s wife); boldness; storing away useful items; watchfulness; and not easily trusting others; these five things are to be learned from a crow.

A person becomes great not be sitting on some high seat, but through higher qualities. Can a crow become an eagle by simply sitting on the top of a palatial building?
