The subject of _property_ is of great extent. It will be necessary to establish the foundation of the rights of acquisition, alienation, and transmission, not in imaginary contracts or a pretended state of nature, but in their subserviency to the subsistence and well-being of mankind. It will not only be curious, but useful, to trace the history of property from the first loose and transient occupancy of the savage, through all the modifications which it has at different times received, to that comprehensive, subtle, and anxiously minute code of property which is the last result of the most refined civilization. I shall observe the same order in considering the society of the sexes as it is regulated by the institution of marriage.[19] I shall endeavour to lay open those unalterable principles of general interest on which that institution rests: and if I entertain a hope that on this subject I may be able to add something to what our masters in morality have taught us, I trust, that the reader will bear in mind, as an excuse for my presumption, that _they_ were not likely to employ much argument where they did not foresee the possibility of doubt. I shall also consider the history[20] of marriage, and trace it through all the forms which it has assumed, to that decent and happy permanency of union, which has, perhaps above all other causes, contributed to the quiet of society, and the refinement of manners in modern times. Among many other inquiries which this subject will suggest, I shall be led more particularly to examine the natural station and duties of the female sex, their condition among different nations, its improvement in Europe, and the bounds which Nature herself has prescribed to the progress of that improvement; beyond which, every pretended advance will be a real degradation.
