Senancour’s work puts forward an image of thought that breaks with the classical paradigmand opens towards the romantic ambition of an immediate, perhaps even immanent thought. It is characterized by its naturalness; it presents a thought of the way more than of the method: a reverie, namely an idea-landscape more than an idea-machine. It is a singular aesthetic Idea, singulative even, which gives access to a form of knowledge as if by intrusion (abduction), and which differentiates it from the philosophical idea by its circumstantiality, its affectivity (aesthetic of the idea).
