Kant et Bolzano. Une «Doppelgängergeschichte»

Bolzano can be called a true «anti-Kant»: his Theory of Science is a systematic counterpoint to the Critique of Pure Reason, and his logical objectivism is the antithesis of the transcendental subjectivity of Critical Philosophy. The autonomy of the Austrian tradition within German-speaking philosophy originates here. However, both Kant and Bolzano are different expressions of the multifaceted Enlightenment: tracing the links between them helps both to better define the reasons for their radical contrasts and to grasp the scope of their legacy; this is also worthwhile in relation to the different approaches to metaphysics that can be linked to the perspectives they opened up.
