" The rise of the buffered identity has been accompanied by an interiorization; that is, not only the Inner/Outer distinction, that between Mind and World as separate loci, which is central to the buffer itself; and not only the development of this Inner/Outer distinction in a whole range of epistemological theories of a mediational type from Descartes to Rorty;' but also the growth of a rich vocabulary of interiority, an inner realm of thought and feeling to be explored. This frontier of self-exploration has grown, through various spiritual disciplines of self-examination, through Montaigne, the development of the modern novel, the rise of Romanticism, the ethic of authenticity, to the point where we now conceive of ourselves as
having inner depths. "
― Charles Taylor , A Secular Age
