I gave my mind entirely up to the impression of music in all its forms, and then returned to reflection and the system of thought expressed in the present work, and thus I arrived at an explanation of the inner nature of music and of the nature of its imitative relation to the world—which from analogy had necessarily to be presupposed—an explanation which is quite sufficient for myself, and satisfactory to my investigation, and which will doubtless be equally evident to any one who has followed me thus far and has agreed with my view of the world. Yet I recognise the fact that it is essentially impossible to prove this explanation, for it assumes and establishes a relation of music, as idea, to that which from its nature can never be idea, and music will have to be regarded as the copy of an original which can never itself be directly presented as idea. I can therefore do no more than state here, at the conclusion of this third book, which has been principally devoted to the consideration of the arts, the explanation of the marvellous art of music which satisfies myself, and I must leave the acceptance or denial of my view to the effect produced upon each of my readers both by music itself and by the whole system of thought communicated in this work. Moreover, I regard it as necessary, in order to be able to assent with full conviction to the exposition of the significance of music I am about to give, that one should often listen to music with constant reflection upon my theory concerning it, and for this again it is necessary to be very familiar with the whole of my system of thought.
