“War precedes commerce. War and commerce are only two different means of achieving the same end, that of getting what one wants. Commerce is simply a tribute paid to the strength of the possessor by the aspirant to possession. It is an attempt to conquer, by mutual agreement, what one can no longer hope to obtain through violence. A man who was always the stronger would never conceive the idea of commerce. It is experience, by proving to him that war, that is, the use of his strength against the strength of others, exposes him to a variety of obstacles and defeats, that leads him to resort to commerce, that is, to a milder and surer means of engaging the interest of others to agree to what suits his own. War is all impulse, commerce, calculation. Hence it follows that an age must come in which commerce replaces war. We have reached this age.”
