Dream Age - Yumenoshiro

This work was written by Yamagata Banto, a townsman and scholar of Osaka in the late Edo period. It consists of 12 volumes and 12 books. It is a representative book of practical learning and enlightenment in the late Edo period. It was originally titled "Atonement for Myself," but was changed to "The Age of Dreams" at the instruction of Nakai Riken, his teacher at Kaitokudo. The initial draft, 6 volumes and 3 books, was published in 1802 (Kyowa 2), and the following year it was revised to 7 volumes and 7 books. With reference to notes by Nakai Chikuzan and Riken, he added drafts and overwritings from before, and in 1820 (Bunsei 3), despite his blindness, he completed the work in 12 volumes. It is divided into sections on astronomy, geography, the Age of the Gods, historical periods, systems, economics, treatises, miscellaneous writings, heresy, no ghosts (volumes 1 and 2), and miscellaneous essays. Heavily influenced by the Kaitokudo school of thought including Goi Ranshu, Nakai Chikuzan and Riken, he distinguished between natural and human phenomena with a thorough rationalism. He also had a deep knowledge of Dutch studies and trusted Western science, supported the heliocentric theory and presented a theory of the light-dark world cosmology, introduced the results of modern medicine, did not believe in the descriptions in the Nihon Shoki before the Ojin period, denied all popular beliefs, and developed the greatest atheism of the Edo period. His arguments are internationally acclaimed today. As he became blind in his later years, there are no handwritten copies, but there are over 50 copies.

江戸後期の大坂の町人学者山片蟠桃(やまがたばんとう)の著作。12巻12冊。江戸後期を代表する実学啓蒙(けいもう)書である。初め『宰我(さいが)の償(つぐのい)』と題したが、懐徳堂(かいとくどう)の師中井履軒(りけん)の指示により『夢の代』と改めた。1802年（享和2）の初稿6巻3冊を補訂して翌年7巻7冊とし、中井竹山(ちくざん)・履軒の筆注を参考として、かねてからの草稿あるいは上書などを加えて1820年（文政3）、失明にも屈せず12巻に大成した。天文、地理、神代(じんだい)、歴代、制度、経済、経論、雑書、異端、無鬼（上・下）、雑論の編成。五井蘭洲(ごいらんしゅう)、中井竹山・履軒ら懐徳堂学統の影響を強く受け、徹底した合理主義にたって自然・人文現象を峻別(しゅんべつ)した。蘭学(らんがく)の知識も深く西欧科学に信頼を寄せ、地動説を支持し明暗界宇宙論を提示、近代医学の成果を紹介し、『日本書紀』の応神(おうじん)紀以前の記述を信ぜず、あらゆる俗信を否定、江戸時代最高の無鬼論（無神論）を展開するなど、その主張は今日国際的に評価されている。晩年失明のため自筆本は存在せず、写本は50点を超える。
