in a 1964 letter to L. J. Mordell as quoted by [C. S. Yogananda, The Life and Times of Bourbaki, June 2015, Resonance, 556–559, http://www.ias.ac.in/article/fulltext/reso/020/06/0556-0559] (quote from p. 558)
“My work is more varied than at any other point in my life. I am still carrying out research in pure mathematics. And I am working on an idea that I had several years ago on negative dimensions. … Negative dimensions are a way of measuring how empty something is. In mathematics, only one set is called empty. It contains nothing whatsoever. But I argued that some sets are emptier than others in a certain useful way. It is an idea that almost everyone greets with great suspicion, thinking I've gone soft in the brain in my old age. Then I explain it and people realise it is obvious. Now I'm developing the idea fully with a colleague. I have high hopes that once we write it down properly and give a few lectures about it at suitable places that negative dimensions will become standard in mathematics.”

Context: So please don't think that I am renouncing anything, I am reasonably faithful in my unfaithfulness and though I have changed, I am the same, and what preys on my mind is simply this one question: what am I good for, could I not be of service or use in some way, how can I become more knowledgeable and study some subject or other in depth? That is what keeps preying on my mind, you see, and then one feels imprisoned by poverty, barred from taking part in this or that project and all sorts of necessities are out of one's reach. As a result one cannot rid oneself of melancholy, one feels emptiness where there might have been friendship and sublime and genuine affection, and one feels dreadful disappointment gnawing at one's spiritual energy, fate seems to stand in the way of affection or one feels a wave of disgust welling up inside. And then one says “How long, my God!”
