In the 18th century in England, nascent psychology competed with a renascent celebration of the mystical nature of inspiration. John Locke's model of the human mind suggested that ideas associate with one another and that a string in the mind can be struck by a resonant idea. Therefore, inspiration was a somewhat random but wholly natural association of ideas and sudden unison of thought. Additionally, Lockean psychology suggested that a natural sense or quality of mind allowed persons to see unity in perceptions and to discern differences in groups. This "fancy" and "wit," as they were later called, were both natural and developed faculties that could account for greater or lesser insight and inspiration in poets and painters.
