XLVI. Thus, with the same confidence with which man admits as true, what is demonstrated to his reason by solid arguments,--and he is then said to be _convinced_,--does he likewise give his assent to the noble inspirations of his heart, not yet depraved by abject inclinations,--and he is then said to be _persuaded_. Thus there are two kinds of truths, equally ascertained, and therefore equally admissible; the one proceeding from intellect and called rational truth, the other formed in the heart, and called moral truth. The source of the latter might also properly be called _good sense_, which in fact acts, in many circumstances of life, in lieu of pure reason. A man endowed with good sense, and who has not yet become a slave to sensual appetites, will not doubt for a moment, even without having ever been acquainted with the proofs, that lying, calumniating, blaspheming, false swearing, robbing, murdering, betraying friendship, country or honour, are culpable and abominable actions. Other truths based on good sense are also the following: the faith we have in friendship, in the rectitude of those who administer justice, in the fidelity of a beloved object, in the tenderness of parents, in the excellence of virtue, and above all, in the wisdom, goodness, and providence of God; all these things we admit within our souls, not in consequence of a cold calculation of the intellect, but through an irresistible impulse of the heart, and in consequence of a sort of presentiment springing from the consciousness of our own noble spirituality, which develops itself and gains force, in proportion as we elevate ourselves above the material propensities to which we are subject as citizens of this earth.
