In the complex and rich dialogue that is The Fixed Idea (1932), Paul Valéry (1871-1945) addresses some of his most beloved, almost obsessive themes. The possibility of a world order, the condition of time, the nature of the intellect, the concept and intuition, the adequacy of language and discourse ... are some of the issues that this almost therapeutic dialogue, between two Characters who, talking, see how the night goes on. First published in 1932, The Fixed Idea has been considered as one of the poet's most brilliant dialogues. Moved as a game, in him discover the ideas their folds, the uselessness of mooring in a safe harbor, that does not exist, and the unavoidable need to do so.
