In the foregoing book we considered these laws in a very simple point of view, and in a very general one,--merely as a system of hardship imposed on the body of the community; and from thence, and from some other arguments, inferred the general injustice of such a procedure. In this we shall be obliged to be more minute; and the matter will become more complex as we undertake to demonstrate the mischievous and impolitic consequences which the particular mode of this oppressive system, and the instruments which it employs, operating, as we said, on this extensive object, produce on the national prosperity, quiet, and security. The stock of materials by which any nation is rendered flourishing and prosperous are its industry, its knowledge or skill, its morals, its execution of justice, its courage, and the national union in directing these powers to one point, and making them all centre in the public benefit. Other than these, I do not know and scarcely can conceive any means by which a community may flourish. If we show that these penal laws of Ireland destroy not one only, but every one, of these materials of public prosperity, it will not be difficult to perceive that Great Britain, whilst they subsist, never can draw from that country all the advantages to which the bounty of Nature has entitled it. To begin with the first great instrument of national happiness and strength, its industry: I must observe, that, although these penal laws do, indeed, inflict many hardships on those who are obnoxious to them, yet their chief, their most extensive, and most certain operation is upon property. Those civil constitutions which promote industry are such as facilitate the acquisition, secure the holding, enable the fixing, and suffer the alienation of property. Every law which obstructs it in any part of this distribution is, in proportion to the force and extent of the obstruction, a discouragement to industry. For a law against property is a law against industry,--the latter having always the former, and nothing else, for its object. Now as to the acquisition of landed property, which is the foundation and support of all the other kinds, the laws have disabled three fourths of the inhabitants of Ireland from acquiring any estate of inheritance for life or years, or any charge whatsoever on which two thirds of the improved yearly value is not reserved for thirty years.
