Researchers often talk about a powerful heuristic potential of the Kantian heritage, but sometimes they do not show concrete examples in defense of this opinion outside Kantianism and Neo- Kantianism.

Jung used Kant’s ideas to construct the theoretical basis of analytical psychology in general and his conception of archetypes in particular, we can see the urgency of Kant’s heritage not only for his direct spiritual successors. In addition the question is discussed: why did Jung claim that epistemologically he took his stand on Kant?
