The idea of Romanticism, which began as an artistic movement, a philosophical theory, and an existentialist attitude, has gotten incorporated in our ordinary language with different luck, and to some extent, ambiguity, to the point that no one is never sure if it is good or bad to be tagged with this adjective. Thus, it is a term needing a certain semantic clarification. And this is what I pretend here, tracking the historical roots of this movement to the end of the 18th century. As Friedrich Schlegel expressed it, Romanticism is the result of the literary work of Goethe, the philosophy of Kant, and more specifically Fichte, and the dissemination from France of revolutionary ideas, within an emerging and juvenile German intellectuality. This way, it could not be further away from that ideal than the maudlin image of an artist hiding in his literature his creative incapacity and the lack of will to transform the historical circumstance. Romanticism has nothing to do either with what Goethe denominated "to the beautiful soul", or what Marx denounces in his critic of the utopian socialisms. Poetry is no hiding place, but rather the essence of the reality seeking fullness, and while this is not achieved, it is only a fragment of itself. And it is the responsibility of the artist, not only to give voice to this trend, but to practically contribute to the task that the world is in itself. This way, art is the recreation of the world beyond its factual limits, until making from all things that which everything wants to be: not only a better world, but the reflection of the fantastic. That indeed, is also called Idealism.
