You can't have good ideas unless you have lots of ideas.

The McCarthy period came along...and many of the other scientists who had been working on these same lines gave up. Probably saying "Why should I sacrifice myself? I am a scientist, I am supposed to be working on scientific things, so I don't need to put myself at risk by talking about these possibilities." And I have said that perhaps I'm just stubborn...
