Of all the Acts that have ever been passed by Parliament, the Toleration Act is perhaps that which most strikingly illustrates the peculiar vices and the peculiar excellences of English legislation. The science of Politics bears in one respect a close analogy to the science of Mechanics. The mathematician can easily demonstrate that a certain power, applied by means of a certain lever or of a certain system of pulleys, will suffice to raise a certain weight. But his demonstration proceeds on the supposition that the machinery is such as no load will bend or break. If the engineer, who has to lift a great mass of real granite by the instrumentality of real timber and real hemp, should absolutely rely on the propositions which he finds in treatises on Dynamics, and should make no allowance for the imperfection of his materials, his whole apparatus of beams, wheels, and ropes would soon come down in ruin, and, with all his geometrical skill, he would be found a far inferior builder to those painted barbarians who, though they never heard of the parallelogram of forces, managed to pile up Stonehenge. What the engineer is to the mathematician, the active statesman is to the contemplative statesman. It is indeed most important that legislators and administrators should be versed in the philosophy of government, as it is most important that the architect, who has to fix an obelisk on its pedestal, or to hang a tubular bridge over an estuary, should be versed in the philosophy of equilibrium and motion. But, as he who has actually to build must bear in mind many things never noticed by D'Alembert and Euler, so must he who has actually to govern be perpetually guided by considerations to which no allusion can be found in the writings of Adam Smith or Jeremy Bentham. The perfect lawgiver is a just temper between the mere man of theory, who can see nothing but general principles, and the mere man of business, who can see nothing but particular circumstances. Of lawgivers in whom the speculative element has prevailed to the exclusion of the practical, the world has during the last eighty years been singularly fruitful. To their wisdom Europe and America have owed scores of abortive constitutions, scores of constitutions which have lived just long enough to make a miserable noise, and have then gone off in convulsions. But in the English legislature the practical element has always predominated, and not seldom unduly predominated, over the speculative. To think nothing of symmetry and much of convenience; never to remove an anomaly merely because it is an anomaly; never to innovate except when some grievance is felt;never to innovate except so far as to get rid of the grievance;never to lay down any proposition of wider extent than the particular case for which it is necessary to provide; these are the rules which have, from the age of John to the age of Victoria, generally guided the deliberations of our two hundred and fifty Parliaments. Our national distaste for whatever is abstract in political science amounts undoubtedly to a fault. But it is, perhaps, a fault on the right side. That we have been far too slow to improve our laws must be admitted. But, though in other countries there may have occasionally been more rapid progress, it would not be easy to name any other country in which there has been so little retrogression.
The Toleration Act approaches very near to the idea of a great English law. To a jurist, versed in the theory of legislation, but not intimately acquainted with the temper of the sects and parties into which the nation was divided at the time of the Revolution, that Act would seem to be a mere chaos of absurdities and contradictions. It will not bear to be tried by sound general principles. Nay, it will not bear to be tried by any principle, sound or unsound. The sound principle undoubtedly is, that mere theological error ought not to be punished by the civil magistrate. This principle the Toleration Act not only does not recognise, but positively disclaims. Not a single one of the cruel laws enacted against nonconformists by the Tudors or the Stuarts is repealed. Persecution continues to be the general rule. Toleration is the exception. Nor is this all. The freedom which is given to conscience is given in the most capricious manner. A Quaker, by making a declaration of faith in general terms, obtains the full benefit of the Act without signing one of the thirty-nine Articles. An Independent minister, who is perfectly willing to make the declaration required from the Quaker, but who has doubts about six or seven of the Articles, remains still subject to the penal laws. Howe is liable to punishment if he preaches before he has solemnly declared his assent to the Anglican doctrine touching the Eucharist. Penn, who altogether rejects the Eucharist, is at perfect liberty to preach without making any declaration whatever on the subject.
