In a state of isolation, our wants exceed our powers;

In consequence of Exchange, our powers exceed our wants.

These propositions show the end and purpose of society. There are two others which guarantee its indefinite improvement:—

In a state of isolation the gain of one may be the loss of another;

In consequence of Exchange, the gain of each is the gain of all.

Is it necessary to prove that, if nature had destined man to a [p117] solitary life, the prosperity of one would have been incompatible with that of another, and the more numerous men had been, the less chance would they have had of attaining prosperity? At all events, we see clearly in what way numbers might have been injurious, and we do not see how they could have been beneficial. And then, I would ask, under what form could the principle of sympathy have manifested itself? How, or on what occasion, could it have been called forth? Could we have even comprehended it?

But men exchange, and Exchange, as we have seen, implies the separation of employments. It gives birth to professions and trades. Each man sets himself to overcome a certain class of obstacles, for the benefit of the Community. Each makes it his business to render a certain description of services. Now, a complete analysis of value demonstrates that each service has value in the first instance in proportion to its intrinsic utility, and afterwards in proportion to the wealth of those to whom it is furnished—that is to say, in proportion as the community to whom the service is rendered has a greater demand for it, and is in a better situation to pay for it. Experience shows us that the artizan, the physician, the lawyer, the merchant, the carrier, the professor, the savant, derive greater returns from their services in Paris, in London, or at New York, than in the Landes of Gascony, or the mountains of Wales, or the prairies of the Far West. And does not this confirm the truth, that each man is more likely to prosper in proportion to the general prosperity of the community in which he lives?

Of all the harmonies which have come under my observation, this is beyond doubt the most important, the finest, the most decisive, the most suggestive. It sums up and includes all the others. This is why I can give only a very incomplete demonstration of it in this place. The whole scope and spirit of this work will establish it; and I shall deem it a fortunate thing if its probability at least is made so apparent as to induce the reader to convince himself of its truth by farther inquiry and reflection.

For it is beyond question that on this turns our decision between natural and artificial Organizations—that on this, and this alone, hangs the solution of the Social Problem. If the prosperity of all be the condition of the prosperity of each, then we can repose with confidence not only on the economic power of free trade, but on its moral force. If men only understood their true interests, restrictions, mercantile jealousies, commercial wars, monopolies, would go down under the influence of public opinion; [p118] and before soliciting the interposition of government in any case, the question would be, not “How am I to be benefited by it?” but “What advantage is likely to result from it to the community?” This last question, I grant, is sometimes elicited by the principle of sympathy; but let men be once enlightened, and it will be called forth by Self-interest. Then we shall be enabled to say with truth that the two motive principles of our nature tend towards the same result—the General Good; and it will be impossible to deny Moral Power to self-interest, and the transactions which spring from it, as far at least as their effects are concerned.

Consider the relations of man to man, family to family, province to province, nation to nation, hemisphere to hemisphere, capitalist to labourer, the man of property to the man of no property,—it seems evident to me that it is impossible to resolve the social problem from any one of these points of view, or even to enter upon its solution, before choosing between these two maxims:—
