It is never my intention to surprise my reader. I detest, as I do death, the man who employs subterfuge in his words and conduct. From the first page of this book, I have expressed myself so plainly and decidedly that all can see the tendency of my thought and hopes; and they will do me the justice to say, that it would be difficult to exhibit more frankness and more boldness at the same time. I do not hesitate to declare that the time is not far distant when this reserve, now so much admired in philosophers–this happy medium so strongly recommended by professors of moral and political science–will be regarded as the disgraceful feature of a science without principle, and as the seal of its reprobation. In legislation and morals, as well as in geometry, axioms are absolute, definitions are certain; and all the results of a principle are to be accepted, provided they are logically deduced. Deplorable pride! We know nothing of our nature, and we charge our blunders to it; and, in a fit of unaffected ignorance, cry out, 'The truth is in doubt, the best definition defines nothing!' We shall know some time whether this distressing uncertainty of jurisprudence arises from the nature of its investigations, or from our prejudices; whether, to explain social phenomena, it is not enough to change our hypothesis, as did Copernicus when he reversed the system of Ptolemy.
