Abstract
Within the tradition of what is called 'the ontological Kant interpretation' the aimof this article is to show that development in Kant's writings before 1770 can be understood on the basis of an explanation of the meaning of the concept of 'real repugnance. In order to meet the shortcomings of a pure logical approach of philosophy Kant emphasizes 'real repugnant' relations, which are to be found in different areas of philosophy, in contrast to logical repugnance . While trying to determine the meaning and role of real repugnance in relation to his metaphysical views of force , space and time and judgement, Kant is forced to renew and to make explicit his view of the relation between experience and metaphysics. Although he recurrent topic of repugnance may be a motive for the development towards a critical approach of philosophy, that establishes new relations between logic, metaphysics and practical philosophy in Critique of Pure Reason, the meaning and function of the concept remain unaffected
