On the other hand, to be pious, is to serve our country with fidelity; it is to be useful to our fellow creatures; to labour to the welfare of society. Every one can put in his claim to this piety, according to his faculties; he who meditates can render himself useful, when he has the courage to announce truth--to attack error--to battle those prejudices which everywhere oppose themselves to the happiness of mankind; it is to be truly useful, it is even a duty, to wrest from the hands of mortals those homicidal weapons which wretched fanatics so profusely distribute among them; it is highly praiseworthy to deprive imposture of its influence; it is loving our neighbour as ourself to despoil tyranny of its fatal empire over opinion, which at all times it so successfully employs to elevate knaves at the expence of public happiness; to erect its power upon the ruins of liberty; to establish unruly passions upon the wreck of public security. To be truly pious, is religiously to observe the wholesome laws of nature; to follow up faithfully those duties which she prescribes to us; in short, to be pious is to be humane, equitable, benevolent: it is to respect the rights of mankind. To be pious and rational at the same time, is to reject those reveries which would be competent to make us mistake the sober counsels of reason.
Thus, whatever fanaticism, whatever imposture may say, he who denieth the solidity of systems which have no other foundation than an alarmed imagination; he who rejecteth creeds continually in contradiction with themselves; he who banisheth from his heart, doctrines perpetually wrestling with nature, always in hostility with reason, ever at war with the happiness of man; he, I repeat, who undeceiveth himself on such dangerous chimeras, when his conduct shall not deviate from those invariable rules which sound morality dictates, which nature approves, which reason prescribes, may be fairly reputed pious, honest, and virtuous. Because a man refuseth to admit contradictory systems, as well as the obscure oracles, which are issued in the name of the gods, does it then follow, that such a man refuses to acknowledge the evident, the demonstrable laws of nature, upon which he depends, of which he in obliged to fulfil the necessary duties, under pain of being punished in this world; whatever he may be in the in the next? It is true, that if virtue could by any chance consist in an ignominious renunciation of reason, in a destructive fanaticism, in useless customs, the atheist, as he is called, could not pass for a virtuous being: but if virtue actually consists in doing to society all the good of which we are capable, this miscalled atheist may fairly lay claim to its practice: his courageous, tender soul, will not be found guilty, for hurling his legitimate indignation against prejudices, fatal to the happiness of the human species.
