Though these are extreme cases, a considerable rise is the rule and not the exception. The advantage of the fixed rent is in fact neutralised by the movable fine. Such figures give point to Crowley's outbursts, "They take our houses over our heads; they buye our groundes out of handes, they reyse our rents, they levy great, yea unreasonable fines."[543] It is not surprising that the programme[544] of agrarian reform put forward by the Yorkshire insurgents in 1536, and by the rebels under Ket in 1549, should have contained a demand for copyhold lands "to be charged with an easy fine, as a capon or a reasonable sum of money." It is not surprising that the Court of Chancery[545] should have been bombarded with petitions to declare or enforce customs limiting the demands which a lord might make of an incoming tenant. It is perhaps more surprising that, in those cases where the fine was by custom uncertain, the rule that a reasonable fine was about two years' rent should not have been enforced by judges at an earlier date and more generally than it seems to have been. For in the sixteenth century, though many old economic ideas are going by the board, public opinion still clings to the conception that there is a standard of fairness in economic dealings which exists independently of the impersonal movements of the market, which honest men can discover, if they please, and which it is a matter of conscience for public authorities to enforce. Even a good Protestant who hates the Pope will admit that there is more than a little in the Canon Law prohibition of usury,[546] and under usury, be it noted, the plain man includes rack-rents, as well as interest on capital and exorbitant prices. If to a modern economist the demand for reasonable fines and rents savours of sentimentality and confusion, he must logically condemn not only the peasants and their champions, but the statesmen; not only Ket and Hales and More and Latimer, but almost every member of every Elizabethan Privy Council. After all, all the precedents are on the side of an attempt to enforce a standard which shall be independent of the result which might be reached by higgling between this landlord and that tenant. Prices are fixed, wages are fixed, the rate of interest is fixed, though the money market is becoming more and more elusive, more and more critical of old-fashioned attempts at interference; the fines which freeholders must pay on admission have been fixed for centuries. Now that copyhold has got the protection of the Courts, it is not unnatural that tenants should ask the State to do with regard to the bargain most affecting them what it already does for bargains of nearly every other kind. It is not unnatural that, even when the fine is not settled by custom at a definite sum, they should demand nevertheless that the Courts should sanction that establishment of a "common rule," which is the ideal of the economically weak in all ages.
