Does it then require an extraordinary effort of genius to comprehend, that what is above the capacity of man, is not made for him; that things supernatural are not made for natural beings; that impenetrable mysteries are not made for limited minds? If theologians are foolish enough to dispute upon objects, which they acknowledge to be unintelligible even to themselves, ought society to take any part in their silly quarrels? Must the blood of nations flow to enhance the conjectures of a few infatuated dreamers? If it is difficult to cure theologians of their madness and the people of their prejudices, it is at least easy to prevent the extravagancies of one party, and the silliness of the other from producing pernicious effects. Let every one be permitted to think as he pleases; but never let him be permitted to injure others for their manner of thinking. Were the rulers of nations more just and rational, theological opinions would not affect the public tranquillity, more than the disputes of natural philosophers, physicians, grammarians, and critics. It is tyranny which causes theological quarrels to be attended with serious consequences.

Those, who extol the importance and utility of Religion, ought to shew us its happy effects, the advantages for instance, which the disputes and abstract speculations of theology can be to porters, artisans, and labourers, and to the multitude of unfortunate women and corrupt servants with which great cities abound. All these beings are religious; they have what is called an implicit faith. Their parsons believe for them; and they stupidly adhere to the unknown belief of their guides. They go to hear sermons, and would think it a great crime to transgress any of the ordinances, to which, in childhood, they are taught to conform. But of what service to morals is all this? None at all. They have not the least idea of Morality, and are even guilty of all the roguery, fraud, rapine, and excess, that is out of the reach of law.

The populace have no idea of their Religion; what they call Religion is nothing but a blind attachment to unknown opinions and mysterious practices. In fact, to deprive people of Religion is to deprive them of nothing. By overthrowing their prejudices, we should only lessen or annihilate the dangerous confidence they put in interested guides, and should teach them to mistrust those, who, under the pretext of Religion, often lead them into fatal excesses.
