Abstract
In this paper the author shows that Emil Lask’s philosophy starts with considering of typical Neo-Kantian’s questions but at the same time it grounds a new philosophical perspective – Post-Neo-Kantianism. The origin of Lask’s research is Heinrich Rickert’s theory of judgment, however Lask finds many new solutions and initiates new ideas adopted from him by Martin Heidegger. The article discuss an innovative elements of Lask’s thought like: problem of the material side of cognition, logic of object, logos-immanency of object, doctrine of the material determination of form, ontological theory of truth, problem of the individual subject. Although Lask does not create ontology, he makes transcendental philosophy to ask ontological questions. When we study his considerations it starts to be obvious that theory of cognition is not possible without ontology.
