If the question relate to one of those exceptional taxes which are imposed on certain products, I grant readily that it is reasonable to impose the same duty on the foreign product. For example, it would be absurd to exempt foreign salt from duty; not that, in an economical point of view, France would lose anything by doing so, but the reverse. Let them say what they will, principles are always the same; and France would gain by the exemption as she must always gain by removing a natural or artificial obstacle. But in this instance the obstacle has been interposed for purposes of revenue. These purposes must be attained; and were foreign salt sold in our market duty free, the Treasury would lose its hundred millions of francs (four millions sterling); and must raise that sum from some other source. There would be an obvious inconsistency in creating an obstacle, and failing in the object. It might have been better to have had recourse at first to another tax than that upon French salt. But I admit that there are certain circumstances in which a tax may be laid on foreign commodities, provided it is not _protective_, but fiscal. But to pretend that a nation, because she is subjected to heavier taxes than her neighbours, should protect herself by tariffs against the competition of her rivals, in this is a sophism, and it is this sophism which I intend to attack. I have said more than once that I propose only to explain the theory, and lay open, as far as possible, the sources of protectionist errors. Had I intended to raise a controversy, I should have asked the protectionists why they direct their tariffs chiefly against England and Belgium, the most heavily taxed countries in the world? Am I not warranted in regarding their argument only as a pretext? But I am not one of those who believe that men are prohibitionists from self-interest, and not from conviction. The doctrine of protection is too popular not to be sincere. If the majority had faith in liberty, we should be free. Undoubtedly it is self-interest which makes our tariffs so heavy; but conviction is at the root of it. "The will," says Pascal, "is one of the principal organs of belief." But the belief exists nevertheless, although it has its root in the will, and in the insidious suggestions of egotism. Let us revert to the sophism founded on taxation. The State may make a good or a bad use of the taxes which it levies. When it renders to the public services which are equivalent to the value it receives, it makes a good use of them. And when it dissipates its revenues without giving any service in return, it makes a bad use of them.
