There has been much noise made about free-thinking; and men have been animated in the contest by a spirit that becomes neither the character of divines nor that of good citizens, by an arbitrary tyrannical spirit under the mask of religious zeal, and by a presumptuous factious spirit under that of liberty. If the first could prevail, they would establish implicit belief and blind obedience, and an Inquisition to maintain this abject servitude. To assert antipodes might become once more as heretical as Arianism or Pelagianism; and men might be dragged to the jails of some Holy Office, like Galilei, for saying they had seen what in fact they had seen, and what every one else that pleased might see. If the second could prevail, they would destroy at once the general influence of religion by shaking the foundations of it which education had laid. These are wide extremes. Is there no middle path in which a reasonable man and a good citizen may direct his steps? I think there is. Every one has an undoubted right to think freely—nay, it is the duty of every one to do so as far as he has the necessary means and opportunities. This duty, too, is in no case so incumbent on him as in those that regard what I call the first philosophy. They who have neither means nor opportunities of this sort must submit their opinions to authority; and to what authority can they resign themselves so properly and so safely as to that of the laws and constitution of their country? In general, nothing can be more absurd than to take opinions of the greatest moment, and such as concern us the most intimately, on trust; but there is no help against it in many particular cases. Things the most absurd in speculation become necessary in practice. Such is the human constitution, and reason excuses them on the account of this necessity. Reason does even a little more, and it is all she can do. She gives the best direction possible to the absurdity. Thus she directs those who must believe because they cannot know, to believe in the laws of their country, and conform their opinions and practice to those of their ancestors, to those of Coruncanius, of Scipio, of Scævola—not to those of Zeno, of Cleanthes, of Chrysippus.
