One can say that the author is an ideological product, since we represent him as the opposite of his historically real function. (When a historically given function is represented in a figure that inverts it, one has an ideological production.) The author is therefore the ideological figure by which one marks the manner in which we fear the proliferation of meaning.
The difference is as great between The optics seeing as the objects seen. All manners take a tincture from our own; Or come discolor'd through our passions shown; Or fancy's beam enlarges, multiplies, Contracts, inverts, and gives ten thousand dyes.Alexander Pope
