Semiosis, Marginal Signs and Trickster - Spinks, C.W.

As signifying creatures, we fear the false creation 'signifying nothing' because, like Macbeth, we think of them as daggers of the mind that raise questions about the reality of our signs, about signs as tools of creation and power, about the dark terrors (and lighter joys) that exist in human desire, and about the signs and the mind.
