Quote from ‘A Brief Intellectual Autobiography by Charles Sanders Peirce’
…philosophical esthetics (which becomes something very different from the study which the noun usually designates)[,] studies the characters which will belong to the phenomenon so far as it is controllable, that is, the characters of what is aimed at. Thus, the question, What is the summum bonum, is regarded as an esthetical question.
