The introduction of machines can, I think, in no other way prove hurtful by making people idle, than by the suddenness of it: and I have frequently observed, that all sudden revolutions, let them be ever so advantageous, must be accompanied with inconveniencies. A safe, honourable, and lasting peace, after a long, dangerous, and expensive war, forces a number of hands to be idle, and deprives them of bread. Peace then may be considered as a machine for defending a nation, at the political loss of making an army idle; yet no body, I believe, will alledge that in order to give bread to soldiers, sutlers, and undertakers, the war should be continued. But here I must observe, that it seems to be a palpable defect in policy, if a statesman shall neglect to find out a proper expedient (at whatever first expence it may be procured) for giving bread to those who, at the risk of their lives, have gone through so many fatigues for the service of their country. This expence should be charged to the account of the war, and a state ought to consider, that as their safety required that numbers should be taken out of the way of securing to themselves a lasting fund of subsistence, which would have rendered them independent of every body, (supposing that to have been the case) she becomes bound by the contract of society, which ties all together, to find them employment. Let me seek for another illustration concerning this matter. I want to make a rampart cross a river, in order to establish a bridge, a mill, a sluice, &c. For this purpose, I must turn off the water, that is, stop the river; would it be a good objection against my improvement to say, that the water would overflow the neighbouring lands, as if I could be supposed so improvident as not to have prepared a new channel for it? Machines stop the river; it is the business of the state to make the new channel, as it is the public which is to reap the benefit of the sluice: I imagine what I have said will naturally suggest an answer to all possible objections against the introduction of machines; as for the advantages of them, they are so palpable that I need not insist upon them. There is however one case in which I think they may be disapproved of; but it seems a chimerical supposition, and is brought in here for no other purpose than to point out and illustrate the principle which, influences this branch of our subject.
