We may as well cut out group theory. That is a subject that will never be of any use in physics.

All discussion of the ultimate nature of things must necessarily be barren unless we have some extraneous standards against which to compare them.

The universe can best be pictured as consisting of pure thought, the thought of what for want of a better word we must describe as a mathematical thinker.

We have already considered with disfavour the possibility of the universe having been planned by a biologist or an engineer; from the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.

...to many it is not knowledge but the quest for knowledge that gives greater interest to thought-to travel hopefully is better than to arrive.

In real science a hypothesis can never be proved true...A science which confines itself to correlating phenomena can never learn anything about the reality underlying the phenomena, while a science which goes further than this and introduces hypotheses about reality, can never acquire certain knowledge of a positive kind about reality; in whatever way we proceed, this is forever denied us.
