I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
I've tried to be totally present, so that when I'm finished with a piece of work, I'm finished. ... The work, once completed, does not need me. The work I'm working on needs my total concentration. The one that's finished doesn't belong to me anymore. It belongs to itself.
