What sort of converts will be produced by this unfeeling logic? "'IChapter ave deeply reflected," suppose, "upon the nature of virtue, and am convinced that a certain proceeding is incumbent on me. But the hangman, supported by an act of parliament, assures me I am mistaken." If I yield my opinion to his dictum, my action becomes modified, and my character also. An influence like this is inconsistent with all generous magnanimity of spirit, all ardent impartiality in the discovery of truth, and all inflexible perseverance in its assertion. Countries, exposed to the perpetual interference of decrees, instead of arguments, exhibit within their boundaries the mere phantoms of men. We can never judge from an observation of their inhabitants what men would be if they knew of no appeal from the tribunal of conscience, and if, whatever they thought, they dared to speak, and dared to act.
At present there will perhaps occur to the majority of readers, but few instances of laws which may be supposed to interfere with the conscientious discharge of duty. A considerable number will occur in the course of the present enquiry. More would readily offer themselves to a patient research.
Men are so successfully reduced to a common standard by the operation of positive law, that, in most countries, they are capable of little more than, like parrots, repeating what others have said. This uniformity is capable of being produced in two ways, by energy of mind and indefatigableness of enquiry, enabling a considerable number to penetrate with equal success into the recesses of truth; and by pusillanimity of temper, and a frigid indifference to right and wrong, produced by the penalties which are suspended over such as shall disinterestedly enquire, and communicate and act upon the result of their enquiries. It is easy to perceive which of these is the cause of the uniformity that prevails in the present instance.
One thing more in enforcement of this important consideration. "I have done something," suppose, "which, though wrong in itself, I believe to be right; or I have done something which I usually admit to be wrong; but my conviction upon the subject is not so clear and forcible as to prevent my yielding to a powerful temptation." There can be no doubt that the proper way of conveying to my understanding a truth of which I am ignorant, or of impressing upon me a firmer persuasion of a truth with which I am acquainted, is by an appeal to my reason. Even an angry expostulation with me upon my conduct will but excite similar passions in me, and cloud, instead of illuminate, my understanding. There is certainly a way of expressing truth with such benevolence as to command attention, and such evidence as to enforce conviction in all cases whatever.
