In this stage of belief, therefore, the liver is the'seat of all emotions and affections, as well as of intellectual functions, and it is only when with advancing anatomical knowledge the functions of the heart and then of the brain come to be recognized that a differentiation of functions takes place which had its outcome in the assignment of intellectual activity to the brain or head, of the higher emotions and affections (as love and courage) to the heart, while the liver was degraded to the rank of being regarded as the seat of the lower emotions and affections, such as jealousy, moroseness and the like.
Richard Strauss, in his edition of Berlioz's works on Instrumentation, paradoxically characterizes the classical orchestral style as that which was derived from chamber-music. Now it, is true that in Haydn's early days orchestras were small and generally private; and that the styles of orchestral and chamber music were not distinct; but surely nothing is clearer than that the whole history of the rise of classical chamber-music lies in its rapid differentiation from the coarse-grained orchestral style with which it began.
On this differentiation of styles rests the whole aesthetics of chamber-music; but the subject is very subtle, and there is much, as for example in Schubert's quartets and his C major quintet, that is inspired by orchestral ideas without in the least vitiating the chamber-music style; though, judged by its appearance on paper, it seems as unorthodox as the notoriously orchestral beginnings of Mendelssohn's quartet in D and quintet in B.
