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

If there is any realm where distinction is especially difficult, it is the realm of childhood memories, the realm of beloved images harbored in memory since childhood. These memories which live by the image and in virtue of the image become, at certain times of our lives and particularly during the quiet age, the origin and matter of a complex reverie: the memory dreams, and reverie remembers.

Two half philosophers will probably never a whole metaphysician make.

The characteristic of scientific progress is our knowing that we did not know.

Nothing is forgotten in the processes of idealization. Reveries of idealization develop, not by letting oneself be taken in by memories, but by constantly dreaming the values of a being whom one would love. And that is the way a great dreamer dreams his double. His magnified double sustains him.

Perhaps it is even a good idea to stir up a rivalry between conceptual and imaginative activity. In any case, one will encounter nothing but disappointments if he intends to make them cooperate. The image can not provide matter for a concept. By giving stability to the image, the concept would stifle its life.

One must always maintain one's connection to the past and yet ceaselessly pull away from it. To remain in touch with the past requires a love of memory. To remain in touch with the past requires a constant imaginative effort.
