The Chapter tries to grasp the meaning of the concept "heresy" in the late Patočka's texts, which concept it interprets as a transgression of the limits of original Husserl's project of phenomenology. Patočka understand intentionality as an openess and the relation to the world conceptualizes in terms of the triple movement of existence, following Husserl's "operative concepts" as discovered by Eugen Film.
In this sense Patočka's phenomenological philosophy presents a certain over-interpretation, nevertheles, it preserves a continuity with the spirit of phenomenology.
