“While there’s life, there is hope.”

Keeping an active mind has been vital to my survival, as has been maintaining a sense of humor.

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.

I’m not in love yet, but when I am, I hope it feels like october.

Hope is the best part of our riches.

Now I really feel the landscape, I can be bold and include every tone of pink and blue: it’s enchanting, it’s delicious, and I hope it will please you.

I just hope that more people will ignore the fatalism of the argument that we are beyond repair. We are not beyond repair. We are never beyond repair.

I hope by the time I’m 30 to have a husband and maybe a baby.

Present, n. That part of eternity dividing the domain of disappointment from the realm of hope.

Our hope is not in the man we put in the White House but in the Man we put on the Cross.

It is only those who hope to transform human beings who end up by burning them, like the waste product of a failed experiment.
