That taxes cannot be legitimately established except by the consent of the people or its representatives, is a truth generally admitted by all philosophers and jurists of any repute on questions of public right, not even excepting Bodin. If any of them have laid down rules which seem to contradict this, their particular motives for doing so may easily be seen; and they introduce so many conditions and restrictions that the argument comes at bottom to the same thing: for whether the people has it in its power to refuse, or the Sovereign ought not to exact, is a matter of indifference with regard to right; and if the point in question concerns only power, it is useless to inquire whether it is legitimate or not. Contributions levied on the people are two kinds; real, levied on commodities, and personal, paid by the head. Both are called taxes or subsidies: when the people fixes the sum to be paid, it is called subsidy; but when it grants the product of an imposition, it is called a tax. We are told in the Spirit of the Laws that a capitation tax is most suited to slavery, and a real tax most in accordance with liberty. This would be incontestable, if the circumstances of every person were equal; for otherwise nothing can be more disproportionate than such a tax; and it is in the observations of exact proportions that the spirit of liberty consists. But if a tax by heads were exactly proportioned to the circumstances of individuals, as what is called the capitation tax in France might be, is would be the most equitable and consequently the most proper for free-men.
