“We say indeed commonly, that the rates of labour and goods have risen since these metals grew plenty; and that the rates of labour and goods were low when the metals were scarce; conceiving the value of the metals as invariable, because the legal names of the pieces, the pounds, shillings or pence, continue to them always the same till a law alters them. But a day’s digging or ploughing was as uneasy to a man a thousand years ago as it is now, though he could not then get so much silver for it: and a barrel of wheat, or beef, was then of the same use to support the human body, as it is now when it is exchanged for four times as much silver. Properly, the value of labour, grain, and cattle are always pretty much the same, as they afford the same uses in life, where no new inventions of tillage or pasturage cause a greater quantity in proportion to the demand.”
