No matter how much experience we may gather in life, we can never in life get the dimension of experience that the imagination gives us. Only the arts and sciences can do that, and of these, only literature gives us the whole sweep and range of human imagination as it sees itself

The simplest questions are the hardest to answer.

Science begins with the world we have to live in, accepting its data and trying to explain its laws. From there, it moves toward the imagination: it becomes a mental construct, a model of a possible way of interpreting experience. The further it goes in this direction, the more it tends to speak the language of mathematics, which is really one of the languages of the imagination, along with literature and music. Art, on the other hand, begins with the world we construct, not with the world we see. It starts with the imagination, and then works toward ordinary experience.

Every human society possesses a mythology which is inherited, transmitted and diversified by literature.

[Science fiction is] a mode of romance with a strong inherent tendency to myth.
