Context: If the roused and insurgent consumers secure the means of production of the salt industry, in all probability they will confiscate this industry for their own profit, and their first thought will be, not to relegate it to free competition, but rather to exploit it, in common, for their own account. They will then name a director or a directive committee to operate the saltworks, to whom they will allocate the funds necessary to defray the costs of salt production. Then, since the experience of the past will have made them suspicious and distrustful, since they will be afraid that the director named by them will seize production for his own benefit, and simply reconstitute by open or hidden means the old monopoly for his own profit, they will elect delegates, representatives entrusted with appropriating the funds necessary for production, with watching over their use, and with making sure that the salt produced is equally distributed to those entitled to it. The production of salt will be organized in this manner.This form of the organization of production has been named communism.When this organization is applied to a single commodity, the communism is said to be partial.When it is applied to all commodities, the communism is said to be complete.But whether communism is partial or complete, political economy is no more tolerant of it than it is of monopoly, of which it is merely an extension.

Variant: I learned this, at least, by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.
