The blank page gives us the right to dream.

Love is never finished expressing itself, and it expresses itself better the more poetically it is dreamed.

In contrast to a dream a reverie cannot be recounted. To be communicated, it must be written, written with emotion and taste, being relived all the more strongly because it is being written down. Here, we are touching the realm of written love. It is going out of fashion, but the benefits remain. There are still souls for whom love is the contact of two poetries, the fusion of two reveries.

At all times and in all fields the explanation by fire is a rich explanation.

Any work of science, no matter what its point of departure, cannot become fully convincing until it crosses the boundary between the theoretical and the experimental: Experimentation must give way to argument, and argument must have recourse to experimentation.

When the image is new, the world is new.

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.
