Science is the business of generating testable hypotheses.

Nobody smart knows what they want to do until they get into their twenties or thirties.

They didn't understand what they were doing. I'm afraid that will be on the tombstone of the human race.

The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

You know, at times like this one feels, well, perhaps extinct animals should be left extinct.

It's not easy to cut through a human head with a hacksaw.

Yes, you have cancer. Yes, your kids are on drugs. Yes, there is an elephant outside your tent. Now the question becomes, What are you going to do about it? Subsequent emotions may not be pleasant, but the hysteria stops. Hysteria accompanies an unwillingness to look at what is really going on; it promotes an unwillingness to look. We feel we are afraid to look, when actually it is not-looking that makes us afraid. The minute we look, we cease being afraid.
