Thinking that he has shattered the title of first occupancy, Henry George undertakes to set up in its place the title of labour. "There can be to the ownership of anything no rightful title which is not derived from the title of the producer, and does not rest on the natural right of the man to himself."[15] The only original title is man's right to the exercise of his own faculties; from this right follows his right to what he produces; now man does not produce land; therefore he cannot have rightful property in land. Of these four propositions the first is a pure assumption, the second is untrue, the third is a truism, and the fourth is as unfounded as the first. Dependently upon God, man has, indeed, a right to himself and to the exercise of his own faculties; but this is a right of action, not of property. By the exercise of this right alone man can never produce anything, never become the owner of anything. He can produce only by exerting his powers upon something outside of himself; that is, upon the goods of external nature. To become the producer and the owner of a product, he must first become the owner of materials. By what title is he to acquire these? In one passage[16] Henry George seems to think that no title is necessary, and refers to the raw material as an "accident," while the finished product is the "essence," declaring that "the right of private ownership attaches the accident to the essence, and gives the right of ownership to the natural material in which the labour of production is embodied." Now this solution of the difficulty is too simple and arbitrary. Its author would have shrunk from applying it universally; for example, to the case of the shoemaker who produces a pair of shoes out of stolen materials, or the burglar who makes an overcoat more useful (and therefore performs a task of production) by transferring it from a warehouse to his shivering back! Evidently Henry George has in mind only raw material in the strict sense, that which has not yet been separated from the storehouse of nature; for he declares in another place that "the right to the produce of labour cannot be enjoyed without the free use of the opportunities offered by nature."[17] In other words, man's title to the materials upon which he is to exercise his faculties, and of which he is to become the owner by right of production, is the title of gift conferred by nature, or nature's God.
