Final answer:
The correct answer is that the 'spiritist approach' option 4 which suggests spiritualizing everything, is NOT an approach to studying the history of philosophy in the context given.
Step-by-step explanation:
The question is asking which of the listed options is NOT an approach to understanding revelation in the context of historiography and philosophy. The four options given are preterist, historicist, futurist, and spiritist, with a fifth option stating that all of the above are approaches to revelation.
Among the three main approaches to the history of philosophy outlined in the provided context—presentist, contextualist, and hermeneutic—none explicitly aligns with the concept of spiritism as being an approach to understanding revelation. Presentist, contextualist, and hermeneutic approaches focus on different methods of evaluating the historical and philosophical significance of texts and ideas, but they do not include deriving knowledge through spirits or spiritualizing everything.
Therefore, the correct answer is that spiritist: we spiritualize everything is NOT an approach to revelation in the provided context of philosophic historiography and how scholars undertake the study of philosophical texts and their relevance today and in their original contexts.
