[515] Erläuterungen über des Herrn Professor Kant Critik der reinen Vernunft (Königsberg, 1784), p. 24. Johann Schulze (or Schultz) was professor of mathematics in Königsberg. He was also Hofprediger, and is frequently referred to as Pastor Schulze. Kant has eulogised him (W. x. p. 128) as “the best philosophical head that I am acquainted with in our part of the world.” In preparing the Erläuterungen, which is a paraphrase or simplified statement of the argument of the Critique, with appended comment, Schulze had the advantage of Kant’s advice in all difficulties. Kant also read his manuscript, and suggested a few modifications (op. cit. pp. 329, 343).
