Philosophy is properly home-sickness the wish to be everywhere at home.
When I started this project, I was a young architect. I was very apprehensive about any changes to the design. Whether I wanted to or not, I learned that you can accept some changes to its form without compromising its intent. But it's a leap of faith that I didn't want to make initially - to put it mildly.
My idea of a perfect surrealist painting is one in which every detail is perfectly realistic, yet filled with a surrealistic, dreamlike mood. And the viewer himself can't understand why that mood exists, because there are no dripping watches or grotesque shapes as reference points. That is what I'm after: that mood which is apart from everyday life, the type of mood that one experiences at very special moments.
If you're teaching a class, you can think about the elementary things that you know very well. These things are kind of fun and delightful. It doesn't do any harm to think them over again. Is there a better way to present them? The elementary things are easy to think about; if you can't think of a new thought, no harm done; what you thought about it before is good enough for the class. If you do think of something new, you're rather pleased that you have a new way of looking at it.The questions of the students are often the source of new research. They often ask profound questions that I've thought about at times and then given up on, so to speak, for a while. It wouldn't do me any harm to think about them again and see if I can go any further now. The students may not be able to see the thing I want to answer, or the subtleties I want to think about, but they remind me of a problem by asking questions in the neighborhood of that problem. It's not so easy to remind yourself of these things.
