On the other hand, Cohen put forward ethical socialism, which is a moral ideal. The transcendental moral law requires that all social systems must become democratic systems and all individuals should become legislators in order to express their unified will and desire. This view has been appreciated by some people in the Second International. William Windelband (1848- 19 15) is the founder of Freiburg School, and he emphasized the humanities. He put forward a widely circulated but controversial view: natural science pursues the establishment of universal laws, so it can be called legislative (universal) knowledge; But historical science seeks to describe unique individual historical events, so it should be called individual knowledge.
Another representative of Fribourg School, Henry H. Richter (1863-1936), inherited this view of Vendel's class, and further proposed that the task of historical science or cultural science is to discover the universally accepted values in culture shown by specific historical events, because it is these cultural values or ideals that determine the historical significance of an event. These viewpoints of neo-Kantianism had a certain influence on natural science, social science and philosophy at that time.
