A philosophy does not play its role as an actor during a recital; it interacts with other philosophies and with other facts, and it cannot know the results of the interaction between itself and other world visions.
~ Umberto Eco

A philosophy has a practical power: it contributes to the changing of the world.
~ Umberto Eco

:::

Philosophical entities exist only insofar as they have been philosophically posited. Outside their philosophical framework, the empirical data that a philosophy organizes lose every possible unity and cohesion.
