This study researched the art-educational thoughts as a modern idea influenced with the social and philosophical transitions in the 19th century. Moreover, this study focused on Frank Lloyd Wright's educational thoughts, because those educational revolutions had appeared as one of the results that Western society's character was rapidly changed by those revolutions, so called, Industrial Revolution, American and French Revolution, and Cultural Revolution of Romanticism, from late 18th century, and eventually because that revolutionary educational ideas had closely and basically many relations with Wright's thought. As a result, even though Wright's education such an apprenticeship was a traditional shape, which was not the old-fashioned educational method discipling to the skillful man, but against the existing education through the self-learning from experiences in nature. That is similar to transcendentalists such as Emerson who searched for having an inspiration in Nature. Namely, Wright himself had struggled against the existing dualistic educational concepts through Wright's monistic thoughts on art-education including architecture based on not naturalism but the philosophy of nature by romantic idealistic philosophers such as Shelling, Fickle, Kant, Hegel including with his Master, Sullivan, and by revolutionary educators such as Freobel, Ruskin, Dewey, and above all by his Unitarian doctrine. However, Wright's thoughts was at that time so radical, and as Wright himself acknowledged that, 'because the philosophy back of it, of course, as you know, is midway I guess between East and West', such all philosophical objects to influence on Wright were so abstruse idea which is usually called 'Romantic' or 'Mystic' that is mingled with East's and West's essence. That is, because Wright himself catched that the theories and methods of the art-educational thoughts would not be easily perceived, and he judged that in a word as a character which could not be taught. After all, Wright's romantic progressivist art-educational thoughts have not been perceived, disseminated in general and widely.
