Opposites are not contradictory but complementary.

Truth and clarity are complementary.

A physicist is just an atom's way of looking at itself.

When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'

The opposite of every great idea is another great idea.

When it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

We are trapped by language to such a degree that every attempt to formulate insight is a play on words.
