It is better to live in a state of impermanence than in one of finality.

Air is the very substance of our freedom, the substance of superhuman joy.... aerial joy is freedom.

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.

Every corner in a house, every angle in a room, every inch of secluded space in which we like to hide, or withdraw into ourselves, is a symbol of solitude for the imagination; that is to say, it is the germ of a room, or of a house.

In order to dream so far, is it enough to read? Isn't it necessary to write? Write as in our schoolboy past, in those days when, as Bonnoure says, the letters wrote themselves one by one, either in their gibbosity or else in their pretentious elegance? In those days, spelling was a drama, our drama of culture at work in the interior of a word.

Reverie is commonly classified among the phenomena of psychic detente. It is lived out in a relaxed time which has no linking force. Since it functions with inattention, it is often without memory. It is a flight from out of the real that does not always find a consistent unreal world.

Of course, thanks to the house, a great many of our memories are housed, and if the house is a bit elaborate, if it has a cellar and a garret, nooks and corridors, our memories have refuges that are all the more clearly delineated. All our lives we come back to them in our daydreams. A psychoanalyst should, therefore, turn his attention to this simple localization of our memories. I should like to give the name of topoanalysis to this auxiliary of pyschoanalysis. Topoanalysis, then would be the systematic psychological study of the sites of our intimate lives.
