Often noted from Montaigne onward is the growing interest in the anatomy of states of mind which in Giambattista Vico reached the point of stress on the importance of reconstructing by vivisection the inner history of one’s own mind. A century separates Vico’s Autobiography and Wordsworth’s Prelude, but they are products of the same impulse. Another century, and Joyce’s Portrait carries the same enterprise a stage further. Vico generalized the process as a means of reconstructing the stages of human culture by the vivisection and contemplation of language itself.
