His lordship pointed out that public opinion has so far advanced that the abstract necessity of prudential limitation is now generally admitted. "Statesmen, reviewers, and ecclesiastics join in a common chorus of exhortation against improvident marriages to the working classes, and preach to them the necessity of deferring the ceremony till they have saved the competency necessary to support the truly British family of ten or twelve children." It is, however, futile to hope that celibacy and continence will furnish the solution of the question. The Protestant world has rejected the idea of a celibate clergy as incompatible with purity and the safety of female virtue. How, then, can we expect that men and women, "with their moral nature more or less stunted, huddled together in dens where the bare conditions of living preclude even elementary ideas of modesty, with none of the pleasures of life save those enjoyed in common with the animals--... these victims of a social state, for which the educated are responsible if they do not use their superior wisdom and knowledge for its redress, to exercise all the self-control of which the celibate ecclesiastic is supposed to be incapable"? The judge then proceeded to argue that, as the evils of over-population were almost universally recognised, the duty of making known to the people the practical method of escaping from them must also be recognised: Why is the philosopher who describes the nature of the disease from which we are suffering, who detects the causes which induce it and the general character of the remedies to be applied, to be regarded as a sage and a benefactor, but his necessary complement in the evolution of a great idea, the man who works out in practice the theories of the abstract thinker, to be denounced as a criminal? It was only when Jenner ventured to act on the theory which he had founded upon his observations that he was denounced and vilified in language which it is now almost impossible to conceive. All history, however, has shown that public opinion advances whilst the law remains stationary; and martyrs must suffer until the law is brought into conformity with the public conscience: A certain number of prosecutions under the law, a certain number of victims to the ignorance or superstition of those who framed it, a certain number of refusals to convict under a growing sense of its unwisdom, injustice and barbarity, seem to be in all societies the stages passed through by laws established for the purpose of coercing the opinions of mankind before they become obsolete, if judge-made, or, if statutes, are repealed as inconsistent with advancing knowledge.
