Books must follow sciences, and not sciences books.”[Proposition touching Amendment of Laws]

It was such a strange tormenting feeling when your daemon was pulling at the link between you; part physical pain deep in the chest, part intense sadness and love. Everyone tested it when they were...

I wish my stove came with a Save As button like Word has. That way I could experiment with my cooking and not fear ruining my dinner.

I ended your experiment. Because you’re not a scientist. You’re a monster. I’m not leaving any of them at your mercy.

Something must be radically wrong with a culture and a civilisation when its youth begins to desert it. Youth is the natural time for revolt, for experiment, for a generous idealism that is eager for...

When we are prevented from attempting seemingly innocuous studies of cancer behavior in humans … we may mark 1966 as the year in which all medical progress ceased.

We must conduct research and then accept the results. If they don’t stand up to experimentation, Buddha’s own words must be rejected.

Doing risk sport had taught me another important lesson: never exceed your limits. You push the envelope and you live for those moments when you’re right on the edge, but you don’t go over. You...

We know a lot nowadays about how to extrapolate from rats to people, but we don’t only have to rely on that. In a sense we’ve made ourselves into experimental animals. There are too many...

There is a difference between what I actually want and what I want to have fantasies about. (…) There is a part of my imagination which is a playground, a playground in which I am...

No human investigation can be called real knowledge if it does not pass through mathematical demonstrations; and if you say that the kinds of knowledge that begin and end in the mind have any value...

Sometimes the best way to learn a lesson isn’t just hearing the words, but putting it into practice by experimenting with it and finding its truth for yourself instead of taking someone else’s word for...

Science, my boy, is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.

Don’t kid yourself by saying that one time can’t make you addicted. It can. I believed it couldn’t too when I first tried meth. I was so, so wrong. The worst part about it is...

I didn’t want a world in which I had to choose between blind human babies and tortured monkey ones. To be frank, that’s the sort of choice I expect science to protect me from, not...

The critical issues here concern what is right, what is just — not the balancing of benefits.

The TV scientist who mutters sadly, “The experiment is a failure; we have failed to achieve what we had hoped for,” is suffering mainly from a bad script writer. An experiment is never a failure...

Absurdity is the ecstasy of intellectualism.

How do they find out with the experiments?”…one way they can find out a whole lot is to make an animal ill and then try different ways to make it better until they find one...

But that was what research and development were like. Full of semi-triumphs and perplexing unforeseen consequences like the whole violent hiccuping thing when conjuring up fire – or the propensity for fillings to fall out...
