Jun Maeda
After forming Key, Maeda worked on the music and scenario for their first title "Kanon" released in 1999, which proved to be very popular in the adult game market in Japan. Beside Maeda, the majority of "Kanon" scenario was written by Naoki Hisaya, but he quit Key shortly after "Kanon" was produced. Following this, Maeda wrote most of the scenario for Key's next title "Air", along with again working as the lyricist and one of the composers for the music featured in the game. After a period of four years in 2004, Key released their third and longest game "Clannad" where Maeda did a vast amount of the writing for the game; in all, Maeda put in around 75% of the work that went into the creation of "Clannad". Also in 2004, Maeda began writing his first manga entitled "Hibiki's Magic", which was first conceived as a short story he wrote as a student. In 2005, Maeda worked on the scenario and music for Key's fifth game "", followed by Key's sixth title "Little Busters!" released in July 2007 which he also worked on in regards to the scenario and music.
Immanuel Kant
Kant discusses the subjective nature of aesthetic qualities and experiences in "Observations on the Feeling of the Beautiful and Sublime" (1764). Kant's contribution to aesthetic theory is developed in the "Critique of Judgment" (1790) where he investigates the possibility and logical status of "judgments of taste." In the "Critique of Aesthetic Judgment," the first major division of the "Critique of Judgment", Kant used the term "aesthetic" in a manner that, according to Kant scholar W.H. Walsh, differs from its modern sense. In the "Critique of Pure Reason", to note essential differences between judgments of taste, moral judgments, and scientific judgments, Kant abandoned the term "aesthetic" as "designating the critique of taste," noting that judgments of taste could never be "directed" by "laws "a priori"." After A. G. Baumgarten, who wrote "Aesthetica" (1750–58), Kant was one of the first philosophers to develop and integrate aesthetic theory into a unified and comprehensive philosophical system, utilizing ideas that played an integral role throughout his philosophy.
