Analogy makes possible the dialogue between people. This dialogue, at the intercultural level and from distinct ontological comprehensions of life, cannot be achieved from a univocal pretension of meaning. Analogy permits, especially at the rhetoric level of Political Philosophy, an adequate interpretation of such complex concepts as people, state or rights. A semantics of these concepts by similarity allows us to advance in the process towards a better interpretation of the other interlocutor’s expression though never reaching identity.
