I am always a different man; a reinterpretation of the man I was yesterday.
I am now convinced that theoretical physics is actually philosophy.
I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.
Those who say that the study of science makes a man an atheist, must be rather silly people.
The belief that there is only one truth and that oneself is in possession of it seems to me the deepest root of all evil that is in the world.
Intellect distinguishes between the possible and the impossible; reason distinguishes between the sensible and the senseless. Even the possible can be senseless.
I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e. g. , about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.
We drown our doubts in dry champagne and soothe our souls with fine cocaine. I don't know why I even care, we get so high and get nowhere.
The intolerant man will not rely on persuasion, or on the worth of the idea. He would deny to others the very freedom of opinion or of dissent which he so stridently demands for himself. He cannot trust democracy.
In my most painful moments on the bike, I am at my most curious and I wonder each and every time how I will respond.
The thing you resist is the thing you need to hear the most.
