238 always, unless there is a simultaneous improvement in production, diminish the share which on a fair division would fall to each individual. An increased production, in default of unoccupied tracts of fertile land, or of fresh improvements tending to cheapen commodities, can never be obtained but by increasing the labour in more than the same proportion. The population must either work harder, or eat less, or obtain their usual food by sacrificing a part of their other customary comforts. Whenever this necessity is postponed, notwithstanding an increase of population, it is because the improvements which facilitate production continue progressive; because the contrivances of mankind for making their labour more effective, keep up an equal struggle with nature, and extort fresh resources from her reluctant powers as fast as human necessities occupy and engross the old.

From this, results the important corollary, that the necessity of restraining population is not, as many persons believe, peculiar to a condition of great inequality of property. A greater number of people cannot, in any given state of civilization, be collectively so well provided for as a smaller. The niggardliness of nature, not the injustice of society, is the cause of the penalty attached to over-population. An unjust distribution of wealth does not even aggravate the evil, but, at most, causes it to be somewhat earlier felt. It is in vain to say, that all mouths which the increase of mankind calls into existence, bring with them hands. The new mouths require as much food as the old ones, and the hands do not produce as much. If all instruments of production were held in joint property by the whole people, and the produce divided with perfect equality among them, and if, in a society thus constituted, industry were as energetic and the produce as ample as at present, there would be enough to make all the existing population extremely comfortable; but when that population had doubled itself, as, with the existing habits of the people, under such an encouragement, it undoubtedly would in little more than
