We cannot doubt that the whole gigantic system which at least maintains a population several times multiplied, which maintains part of it in wealth and a large proportion in reasonable comfort, has been due to the labours of many men, each working for his own interest and animated chiefly by the desire of wealth. So much remains true of the economist's doctrine of the natural harmony between individual and public interest. In this case, as in the case of governments, we may, perhaps, say that men acted from motives which must be called selfish, in this sense at least, that they thought of little but their own interests; but that, at the same time, their own interests compelled them to work in a direction which promoted, more or less, the interests of others. I add, briefly, that these are only instances of what we may call the general rule: namely, that morality begins from an external or unrecognised conformity of interests, and ends by recognising and adopting, as motives, the consequences which, in the earlier stage, seemed to be internal or accidental consequences. I begin by helping a man because circumstances make it useful to myself, and I end--and only become truly moral when I end--by doing what is useful to him, because it is useful to him. When, indeed, I have reached that point, my end itself is profoundly modified; it becomes much wider, and yet only regulates and directs to new channels a great deal of the corresponding conduct. The consideration of this modification--of the change which should take place when a man not only pursues such conduct as is beneficial on the whole to a country, but pursues it with a view to the beneficial consequences--brings us back to the question of luxury. The bare pursuit of wealth as the end of existence implies, of course, indifference to the means by which it is produced; an equal readiness, for example, to grow rich by cheating my neighbour, or by actually producing a greater quantity of useful produce. It is consistent with a simple desire to enlarge my business without reference to the effect upon the persons I employ, as when manufacturers enriched themselves by cruel exploitation of the labour of infants. But if we hope for a state of things in which an employer should consider himself as essentially part of the national organism, as increasing his own wealth only by such means as would be also advantageous to the comfort of the nation generally, the pursuit of wealth would become moralised.
