This paper begins by highlighting the respective roles of the intuitive (Sensitivity) and the discursive (Intellect) which lay at the fondation of Critical Thinking. This question is metaphysical in a kantian sense. Clearly, Kant's Architectonics allows us to underline the concepts of space and time. With that in mind, the Lambertian notion of Simulacrum can be ( successfully) applied to Lesniewski and Kant. Lambert's theory enables us to rethink Frege's disputed point of spatial and temporal intuition. Here we explain how the (concept of) quasi-Simulacrum or second order Simulacrum allows us to expose the impossibility of ontology in Kant. In conclusion we show why there are no other Simulacra beyond n = 2.
