We become more and more aware that what we think about the world is not what the world is but what the human animal sees of the world. - Jacob Bronowski

To imagine is the characteristic act, not of the poet's mind, or the painter's, or the scientist's, but of the mind of man.

The symbol and the metaphor are as necessary to science as to poetry.

On the one hand, all science, and indeed all thinking starts from and rests upon notions of order; what marks the Middle Ages is that their order was always a hierarchy. And on the other hand what marks the scientific view is not that it turned to the mechanism of causes, but that it saw the world as a mechanism at all—a machine of events.
