Kant’s Logic of Knowledge
It is currently taken for granted that epistemic thinking is necessarily related to the object of intuition. The view originates with Immanuel Kant. According to Kant, to know something presuposes to be related to sensual intuition. Concept is determined by Kant as something different from intution and as the second basic feature of knowing something. It is always only from the relationship of conceptual thinking to intuition that knowledge results. It takes place in the synthesis, i.e. in the synthetic judgement, which thus provides the very basis of knowledge. In contrast, such a basis cannot be provided either by the analytical judgment à la Leibniz or by the psychologically empirical judgement à la Hume.
