Daydream transports the dreamer outside the immediate world to a world that bears the mark of infinity. - Gaston Bachelard

Well-determined centers of revery are means of communication between men who dream as surely as well-defined concepts are means of communications between men who think.

But each poetic world is not a pure invention, it is a possibility of nature.
Imagination is itself immanent in the real. It is not a state. It is human existence itself.

Ideas are invented only as correctives to the past. Through repeated rectifications of this kind one may hope to disengage an idea that is valid.
