The Beautiful – An Introduction to Psychological Esthetics [EPUB ebook] 

I have tried in this little volume to explain aesthetic preference, particularly as regards visible shapes, by the facts of mental science. But my explanation is addressed to readers in whom I have no right to expect a previous knowledge of psychology, particularly in its more modern developments. I have therefore based my explanation of the problems of aesthetics as much as possible upon mental facts familiar, or at all events easily intelligible, to the lay reader.
