The end of the natural law, therefore, is to render man inexcusable, and may be not improperly defined-the judgment of conscience distinguishing sufficiently between just and unjust, and by convicting men on their own testimony, depriving them of all pretext for ignorance. So indulgent is man toward himself, that, while doing evil, he always endeavours as much as he can to suppress the idea of sin.
