Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
One of the things I like about performing on the stage is that it is a kind of meditative experience. Time does stand still. You have no concept or feeling of the passing of two or three hours' time. It's all kind of one present moment, which is a kind of a description of meditation.
