I consider "Development" and "Individuality" two fundamental principles in F. Meineck's view of History. As "Individuality", the latter concept, having been studied in the previous issue of " Historical Sciences " (史學), I have intended here to discuss "Development" and explain how these two concepts are united in Meinecke's thought. As I referred in the preceding article, "Individuality" is of the immanent character, and it can be grasped only by means of intuition (or prerecognition Ahnung), not by means of experience nor by logical thinking. The question, therefore, lies in how we can unite these opposite concepts. From careful examination of his concept of "Individuality", we may conclude that these opposite concepts could be brought to unity through "Individalization" of development, which is only possible through the medium of "Personalisation". Meinecke inherited this principle of "Personalisation" from German Romanticism. The Universal History, conceived as ultimate aspect of historical development, can be individalised. Thus the principle of "Individuality" is kept ccnsequent throughout Meinecke's thought on History, its apperant contradiction being cleared out through the application of the concept "Personalization".
