What is this diplomacy? It is a costly engine for maintaining peace. It is a remarkable instrument used by civilised nations for the purpose of preventing war. Unless it be used for that purpose, unless it be used to appease the angry passions of individual men, and check the feelings which arise out of national resentment, unless it be used for that purpose, it is an instrument not only costly but mischievous. If then your application of diplomacy be to fester every wound, to provoke instead of soothing resentments, to place a minister in every court of Europe for the purpose, not of preventing quarrels, or of adjusting quarrels, but for the purpose of continuing an angry correspondence in this place, or of promoting what is supposed to be an English interest by keeping up conflicts with the representatives of other powers, then I say that not only is the expenditure upon this costly instrument thrown away, but this great engine, used by civilised society for the purpose of maintaining peace, is perverted into a cause of hostility and war.

Each town and each country will command the amount of currency which it requires for its own purposes, undisturbed in the slightest degree by consulting its manifest interest, namely, by purchasing that which it wants in the cheapest market. [Derisive cheers.] Yes, by purchasing that which it wants in the cheapest market. You consider this a very low and unworthy principle; that it is a doctrine of the Manchester school; that it is a novel doctrine of some speculative political philosophers, and that it may be safely rejected. But this doctrine of purchasing in the cheapest market is not a doctrine of speculative philosophers only. It is not a doctrine introduced by modern economists. It is, no doubt, a doctrine sanctioned expressly and directly by the authority of Adam Smith. It is the doctrine of Say and of Hume. It is opposed to a doctrine which was fashioned some eighty or ninety years since, of which such writers as Montesquieu and Voltaire were the patrons; but Smith, and Say, and Hume, demonstrated the true principles which ought to regulate the commercial policy of a nation.

I gladly avail myself also of this, a legitimate opportunity, of making a more public appeal—of addressing myself, through you, to that great and intelligent class of society of which you are a portion, and a fair and unexceptionable representative—to that class which is much less interested in the contentions of party, than in the maintenance of order and the cause of good government
