instead of becoming clear. It ought to be the part of the State to prevent, and, above all, to repress artifice and fraud; that is, to secure liberty, and not to violate it. I have enlarged a little upon exchange, although loan is my principal object: my excuse is, that I conceive that there is in a loan an actual exchange, an actual service rendered by the lender, and which makes the borrower liable to an equivalent service,—two services, whose comparative value can only be appreciated, like that of all possible services, by freedom. Now, if it is so, the perfect lawfulness of what is called house-rent, farm-rent, interest, will be explained and justified. Let us consider the case of loan.
Suppose two men exchange two services or two objects, whose equal value is beyond all dispute. Suppose, for example, Peter says to Paul, "Give me ten sixpences, I will give you a five-shilling piece." We cannot imagine an equal value more unquestionable. When the bargain is made, neither party has any claim upon the other. The exchanged services are equal. Thus it follows, that if one of the aprties wishes to introduce into the bargain an additional clause, advantageous to himself, but unfavourable to the other party, he must agree to a second clause, which shall re-establish the equilibrium, and the law of justice. It would be absurd to deny the justice of a second clause of compensation. This granted, we will suppose that Peter, after having said to Paul, "Give me ten sixpences, I will give you a crown," adds, "You shall give me
