It was in the second edition of his book that Malthus expanded his treatment of the preventive checks, thus softening the somewhat harsher aspects of his first edition. It is very important that we should grasp his exact meaning. We therefore make no apology for frequently quoting his views on one point which is in itself very important, but upon which the ideas of the reverend pastor of Haileybury have been so often misrepresented.

The preventive check must be taken to imply moral restraint. But does this mean abstaining from sexual intercourse during the period of marriage after the birth, say, of three children, which may be taken as sufficient to keep the population stationary or moderately progressive? We cannot find that Malthus ever advocated such abstention. We have already seen that he considered six children a normal family, implying the doubling of the population every twenty-five years. Neither is it suggested that six should be the maximum, for he adds: “It may be said, perhaps, that even this degree of prudence might not always avail, as when a man marries he cannot tell what number of children he shall have, and many have more than six. This is certainly true.” (P. 536.)

But where does moral restraint come in? This is how he defines it: “Restraint from marriage which is not followed by irregular gratifications may properly be termed moral restraint” (p. 9); and to avoid any possible misunderstanding he adds a note: “By moral restraint I would be understood to mean a restraint from marriage from prudential motives with a conduct strictly moral during the period of this restraint, and I have never intentionally deviated from this sense.” All this is perfectly explicit. He means abstention from all sexual intercourse outside the bonds of marriage, and the postponement of marriage itself until such time as the man can take upon himself the responsibility of bringing up a family—and even the complete renunciation of marriage should the economic conditions never prove favourable.

Malthus unceremoniously rejected the methods advocated by those who to-day bear his name, and expressly condemned all who favoured the free exercise of sexual connection, whether within or without the marriage bond, through the practice of voluntary sterilization. All these preventive methods are grouped together as vices and their evil effects contrasted with the practice of moral restraint. Malthus is equally explicit on this point. “Indeed, I should always particularly reprobate any artificial and unnatural modes of checking population. The restraints which I have recommended are quite of a different character. They are not only pointed out by reason and sanctioned by religion, but tend in the most marked manner to stimulate industry.” (P. 572.) And he adds these significant words, so strangely prophetic so far as France is concerned: “It might be easy to fall into the opposite mistake and to check the growth of population altogether.”

It is quite needless to add that if Malthus thus made short work of conjugal frauds he all the more strongly condemned that other preventive method, namely, the institution of a special class of professional prostitutes.[298] He would similarly have condemned the practice of abortion, of which scarcely anything was heard in his day, but which now appears like a scourge, taking the place of infanticide and the other barbarous practices of antiquity. Criminal law seems powerless to suppress it, and it has already received the sanction of a new morality.

But apart from the question of immoral practices, did Malthus really believe that moral restraint as he conceived of it would constitute an effective check upon population?

He doubtless was anxious that it should be so, and he tried to rouse men to a holy crusade against this worst of all social evils. “To the Christian I would say that the Scriptures most clearly and precisely point it out to us as our duty to restrain our passions within the bounds of reason.… The Christian cannot consider the difficulty of moral restraint as any argument against its being his duty.” (P. 452.) And to those who wish to follow the dictates of reason rather than the observances of religion he remarks: “This virtue [chastity] appears to be absolutely necessary in order to avoid certain evils which would otherwise result from the general laws of nature.” (P. 452.)[299]

At bottom he was never quite certain as to the efficacy of moral restraint. The threatening hydra always peered over the fragile shield of pure crystal with which he had hoped to do battle.[300] He also felt that celibacy might not merely be ineffective, but would actually prove dangerous by provoking the vices it was intended to check. Its prolongation, or worse still its perpetuation, could never be favourable to good morals.

Malthus was faced with a terrible dilemma, and the uncompromising ascetic is forced to declare himself a utilitarian philosopher of the Benthamite persuasion. He has now to condone those practices which satisfy the sexual instinct without involving maternity, although at an earlier stage he characterised them as vices. It seemed to him to be the lesser of two evils, for over-population[301] is itself the cause of much immorality, with its misery, its promiscuous living and licence. All of which is very true.[302] At the same time the rule of conduct now prescribed is no longer that of “perfect purity.” It is, as he himself says, the grand rule of utility. “It is clearly our duty gradually to acquire a habit of gratifying our passion, only in that way which is unattended with evil.” (P. 500.) These concessions only served to prepare the way for the Neo-Malthusians.

Malthus gives us a picture of man at the cross-roads. Straight in front of him lies the road to misery, on the right the path of virtue, while on the left is the way of vice. Towards the first man is impelled by a blind instinct. Malthus warns him to rein in his desires and seek escape along either by-road, preferably by the path on his right. But he fears that the number of those who will accept his advice and choose “the strait road of salvation” will be very small. On the other hand, he is unwilling to admit, even in the secrecy of his own soul, that most men will probably follow the road that leads on to vice, and that masses will rush down the easy slope towards perdition. In any case the prospect is anything but inviting.
