Explanation:

Correct Option 3: Ernst Griedmann

He used the label "Philosophical Historism" to refer to a specific approach to legal theory and jurisprudence, especially in the context of the German legal tradition that viewed law as a product of historical development rather than abstract reasoning.

This school contrasts with natural law theory and analytical positivism, emphasizing that law evolves organically with the history and culture of a people.

In Summary:

• Who named the school “Philosophical Historism”?

  • Ernst Griedmann (as correctly identified by you)

• Key idea: Law is rooted in the history and culture of a nation — not in eternal, rational principles.
