Men are tempted to labour, and to practise lucrative arts, by motives of interest. Secure to the workman the fruit of his labour, give him the prospects of independence or freedom, the public has found a faithful minister in the acquisition of wealth, and a faithful steward in hoarding what he has gained. The statesman, in this, as in the case of population itself, can do little more than avoid doing mischief. It is well, if, in the beginnings of commerce, he knows how to repress the frauds to which it is subject. Commerce, if continued, is the branch in which men, committed to the effects of their own experience, are least apt to go wrong.
The trader, in rude ages, is short sighted, fraudulent and mercenary; but in the progress and advanced state of his art, his views are enlarged, his maxims are established: he becomes punctual, liberal, faithful, and enterprising; and in the period of general corruption, he alone has every virtue, except the force to defend his acquisitions. He needs no aid from the state, but its protection; and is often in himself its most intelligent and respectable member. Even in China, we are informed, where pilfering, fraud, and corruption, are the reigning practice with all the other orders of men, the great merchant is ready to give, and to procure confidence: while his countrymen act on the plans, and under the restrictions, of a police adjusted to knaves, he acts on the reasons of trade, and the maxims of mankind.
If population be connected with national wealth, liberty and personal security is the great foundation of both: and if this foundation be laid in the state, nature has secured the increase and industry of its members; the one by desires the most ardent in the human frame, the other by a consideration the most uniform and constant of any that possesses the mind. The great object of policy, therefore, with respect to both, is, to secure to the family its means of subsistence and settlement; to protect the industrious in the pursuit of his occupation; to reconcile the restrictions of police, and the social affections of mankind, with their separate and interested pursuits.
In matters of particular profession, industry, and trade, the experienced practitioner is the master, and every general reasoner is a novice. The object in commerce is to make the individual rich; the more he gains for himself, the more he augments the wealth of his country. If a protection be required, it must be granted; if crimes and frauds be committed, they must be repressed; and government can pretend to no more. When the refined politician would lend an active hand, he only multiplies interruptions and grounds of complaint; when the merchant forgets his own interest to lay plans for his country, the period of vision and chimera is near, and the solid basis of commerce withdrawn. He might be told, that while he pursues his advantage, and gives no cause of complaint, the interest of commerce is safe.
