Physics, owing to the simplicity of its subject matter, has reached a higher state of development than any other science.

That which exists through itself is called The Eternal. The Eternal has neither name nor shape. It is the one essence, the one primal spirit. Essence and life cannot be seen. They are contained in the light of heaven. The light of heaven cannot be seen. It is contained in the two eyes.

Physics is mathematical not because we know so much about the physical world, but because we know so little; it is only its mathematical properties that we can discover.

The solution of the difficulties which formerly surrounded the mathematical infinite is probably the greatest achievement of which our age has to boast.

It can be shown that a mathematical web of some kind can be woven about any universe containing several objects. The fact that our universe lends itself to mathematical treatment is not a fact of any great philosophical significance.

Science, in its ultimate ideal, consists of a set of propositions arranged in a hierarchy, the lowest level of the hierarchy being concerned with particular facts, and the highest with some general law, governing everything in the universe. The various levels in the hierarchy have a two-fold logical connection, travelling one up, one down; the upward connection proceeds by induction, the downward by deduction.

We must be sceptical even of our scepticism.
