"Any valuable object in order to appeal to our sense of beauty must conform to the requirements of beauty and of expensiveness both. But this is not all. Beyond this the canon of expensiveness also affects our tastes in such a way as to inextricably blend the marks of expensiveness, in our appreciation, with the beautiful features of the object, and to subsume the resultant effect under the head of an appreciation of beauty simply. The marks of expensiveness come to be accepted as beautiful features of the expensive articles. They are pleasing as being marks of honorific costliness, and the pleasure which they afford on this score blends with that afforded by the beautiful form and color of the object."
