I shall confirm it in the following chapter, by proving the impossibility of all social inequality.
What have we shown so far?
Things so simple that really they seem silly:-- That, as the traveller does not appropriate the route which he traverses, so the farmer does not appropriate the field which he sows; That if, nevertheless, by reason of his industry, a laborer may appropriate the material which he employs, every employer of material becomes, by the same title, a proprietor; That all capital, whether material or mental, being the result of collective labor, is, in consequence, collective property; That the strong have no right to encroach upon the labor of the weak, nor the shrewd to take advantage of the credulity of the simple; Finally, that no one can be forced to buy that which he does not want, still less to pay for that which he has not bought; and, consequently, that the exchangeable value of a product, being measured neither by the opinion of the buyer nor that of the seller, but by the amount of time and outlay which it has cost, the property of each always remains the same.
Are not these very simple truths?
Well, as simple as they seem to you, reader, you shall yet see others which surpass them in dullness and simplicity.

For our course is the reverse of that of the geometricians: with them, the farther they advance, the more difficult their problems become; we, on the contrary, after having commenced with the most abstruse propositions, shall end with the axioms.
But I must close this chapter with an exposition of one of those startling truths which never have been dreamed of by legists or economists.
% 8 .-- That, from the Stand-point of Justice, Labor destroys Property.
This proposition is the logical result of the two preceding sections, which we have just summed up.
The isolated man can supply but a very small portion of his wants; all his power lies in association, and in the intelligent combination of universal effort.

The division and co-operation of labor multiply the quantity and the variety of products; the individuality of functions improves their quality.
There is not a man, then, but lives upon the products of several thousand different industries; not a laborer but receives from society at large the things which he consumes, and, with these, the power to reproduce.

Who, indeed, would venture the assertion, "I produce, by my own effort, all that I consume; I need the aid of no one else"?
The farmer, whom the early economists regarded as the only real producer--the farmer, housed, furnished, clothed, fed, and assisted by the mason, the carpenter, the tailor, the miller, the baker, the butcher, the grocer, the blacksmith, &c.,--the farmer, I say, can he boast that he produces by his own unaided effort?
The various articles of consumption are given to each by all; consequently, the production of each involves the production of all.
One product cannot exist without another; an isolated industry is an impossible thing.

What would be the harvest of the farmer, if others did not manufacture for him barns, wagons, ploughs, clothes, &c.?
Where would be the savant without the publisher; the printer without the typecaster and the machinist; and these, in their turn, without a multitude of other industries ?...
