“At one time I thought the most important thing was talent. I think now that — the young man or the young woman must possess or teach himself, train himself, in infinite patience, which is to try and to try and to try until it comes right. He must train himself in ruthless intolerance. That is, to throw away anything that is false no matter how much he might love that page or that paragraph. The most important thing is insight, that is ... curiosity to wonder, to mull, and to muse why it is that man does what he does. And if you have that, then I don't think the talent makes much difference, whether you've got that or not.

[Press conference, University of Virginia, May 20, 1957]”
