In the theoretical philosophy of Immanuel Kant, the term object has an extensive and far-reaching significance, and it can therefore be understood as a theory of objects. This becomes particularly clear when it is observed that all of his guidelines can be traced to different concepts of objects and their combination. With his concept of the object of experience, he attempts to mediate incompatible aspects in this: in relation to the object of experience, we have apodictic claims but at the (...) same time our knowledge of the object develops and contains the possibility of historical progress. This theory of objects was elaborated by Kant with regard to natural science and the claim of its metaphysical foundation. For this reason, Kant’s concept of object is inherently linked with his concept of science. Astronomy is at the core of his investigation, because it represents a perfect example of a so-called proper and rational natural science. (shrink)
