Shelley is often considered as a significant English Romantic poet. The concept that passion, rather than reason, should rule people was one of the most contentious literary figures of the early nineteenth century. His friend and mentor John Keats died at the age of 26 after writing only two years of formal education. No one else except Keats himself has ever been quoted as saying that he was an "infinite genius". Nevertheless, there are many similarities between them: both were passionate about poetry; both had severe health problems that prevented them from working for long periods of time; and finally, both were dead within three years of being born. In addition to being a poet, Keats was also a successful medical practitioner who spent much of his time traveling around England treating patients. He also attended several meetings of the leading circle of London-based artists and writers known as the "Keats Circle", which included some of Shelley's closest friends. It has been suggested that this may have influenced Shelley to invite Keats to live with him and his wife at their country house in West Sussex, where they could have devoted themselves to art and literature without worrying about money or employment. When you include Keats in its discussion of poets because he was his contemporary, it can be argued that the Romantic movement also includes him.
