Each by experience raises himself to the science; or rather the science is nothing more than experience, scrupulously observed and methodically expounded.
But _your_ theory is _theory_ in the worst sense of the word.

You imagine procedures which are sanctioned by the experience of no living man, and then call to your aid constraint and prohibition.

You cannot avoid having recourse to force; because, wishing to make men produce what they can _more advantageously_ buy, you require them to give up an advantage, and to be led by a doctrine which implies contradiction even in its terms.
I defy you too, to take this doctrine, which by your own avowal would be absurd in individual relations, and apply it, even in speculation, to transactions between families, towns, departments, or provinces.

You yourselves confess that it is only applicable to internal relations.
Thus it is that you are daily forced to repeat: "Principles can never be universal.

What is _well_ in an individual, a family, commune, or province, is _ill_ in a nation.
