The evil arising from mental improvement can be corrected only by a still farther progress in that very improvement. Either morality is a fable, or the more enlightened we are, the more attached to it we become.[Le mal des lumières ne peut se corriger qu’en acquérant plus de lumières encore. Ou la morale serait une idée fausse, ou il est vrai que plus on s’éclaire, plus on s’y attache. ]
