 Second, Hartshorne frequently uses the history of philosophy to see which of the logically possible options made available by position matrices have been defended before so as to avail ourselves of the insights of others in the effort to examine in detail the consistency of these positions and to assess their consequences. Nonetheless, those logically possible options that have not historically found support should be analyzed both in terms of internal consistency and practical ramifications. It should be noted that Hartshorne’s use of the history of philosophy often involves lesser known views of famous thinkers (like Plato’s belief in God as the soul for the body of the whole natural world, or Leibniz’s defense of panpsychism) as well as the thought of lesser known thinkers (such as Faustus Socinus, Nicholas Berdyaev, Mohammed Iqbal, or Jules Lecquier).
