This freedom, then, which is the essence of our being, has to be controlled. But it is difficult to see what power we are to invoke to help us, since every restraint of private opinion or public law has been derided, and Montaigne never ceases to pour scorn upon the misery, the weakness, the vanity of human nature. Perhaps, then, it will be well to turn to religion to guide us? "Perhaps" is one of his favourite expressions; "perhaps" and "I think" and all those words which qualify the rash assumptions of human ignorance. Such words help one to muffle up opinions which it would be highly impolitic to speak outright.
