Every word, indeed, begins by denoting a concrete object or a material action; but by degrees the meaning of the word is refined into an abstract relation or a pure idea. If, then, the above law holds good here, it should be stated as follows: "A comic effect is obtained whenever we pretend to take literally an expression which was used figuratively"; or, "Once our attention is fixed on the material aspect of a metaphor, the idea expressed becomes comic."
