This book takes the reader on a grand tour of the empirical research concerning the personality trait of appreciation of beauty. It particularly focuses on engagement with natural beauty, engagement with artistic beauty, and engagement with moral beauty. The book addresses philosophers’ thoughts about beauty, especially the special emphasis on the intimate relationship between love and beauty; appreciation of beauty from an evolutionary standpoint; and the emerging science of neuroaesthetics. The book concludes with a consideration of beauty and pedagogy/andragogy, as well as methodologies to increase appreciation of beauty.
