 The history of philosophy is not only shaped by the necessary self-expression of reason, but also by the causal necessity of cultural history. The cultural determinants of philosophical thinking lead to “problem-convolutions” (1891: 11), in which various, conceptually unrelated philosophical questions merge with one another. Windelband also emphasizes that the “individual factor” of the philosopher’s character and personality is relevant for how philosophical problems and concepts are articulated in a given historical moment (1891: 12)
