Slavery furnishes a second striking example of the impotence of philosophical and religious sentiments in a conflict with the energetic activity of self-interest.

This may seem sad to some modern schools which seek the reformation of society in self-denial. Let them begin by reforming the nature of man.

In the Antilles the masters, from father to son, have, since slavery was established, professed the Christian religion. Many times a day they repeat these words: "All men are brothers. Love thy neighbor as thyself; in this are the law and the prophets fulfilled." Yet they hold slaves, and nothing seems to them more legitimate or natural. Do modern reformers hope that their moral creed will ever be as universally accepted, as popular, as authoritative, or as often on all lips as the Gospel? If that has not passed from the lips to the heart, over or through the great barrier of self-interest, how can they hope that their system will work this miracle?

Well, then, is slavery invulnerable? No; self-interest, which founded it, will one day destroy it, provided the special interests which have created it do not stifle those general interests which tend to overthrow it.

Another truth demonstrated by political economy is, that free labor is progressive, and slave labor stationary. Hence the triumph of the first over the second is inevitable. What has become of the cultivation of indigo by the blacks?

Free labor, applied to the production of sugar, is constantly causing a reduction in the price. Slave property is becoming proportionately less valuable to the master. Slavery will soon die out in America unless the price of sugar is artificially raised by legislation. Accordingly we see to-day the masters, their creditors and representatives, making vigorous efforts to maintain these laws, which are the pillars of the edifice.

Unfortunately they still have the sympathy of people among whom slavery has disappeared, from which circumstance the sovereignty of public opinion may again be observed. If public opinion is sovereign in the domain of force, it is much more so in the domain of fraud. Fraud is its proper sphere. Stratagem is the abuse of intelligence. Imposture on the part of the despoiler implies credulity on the part of the despoiled, and the natural antidote of credulity is truth. It follows that to enlighten the mind is to deprive this species of spoliation of its support.

I will briefly pass in review a few of the different kinds of spoliation which are practiced on an exceedingly large scale. The first which presents itself is spoliation through the avenue of superstition. In what does it consist? In the exchange of food, clothing, luxury, distinction, influence, power—substantial services for fictitious services. If I tell a man: "I will render you an immediate service," I am obliged to keep my word, or he would soon know what to depend upon, and my trickery would be unmasked.

But if I should tell him, "In exchange for your services I will do you immense service, not in this world but in another; after this life you may be eternally happy or miserable, and that happiness or misery depends upon me; I am a vicar between God and man, and can open to you the gates of heaven or of hell;" if that man believes me he is at my mercy.

This method of imposture has been very extensively practiced since the beginning of the world, and it is well known to what omnipotence the Egyptian priests attained by such means.
