And endless infamy!"
They do not celebrate the triumphs of their enemies as their own: it is with them a more feeling disputation. They never give an inch of ground that they can keep; they keep all that they can get; they make no concessions that can redound to their own discredit; they assume all that makes for them; if they pause it is to gain time; if they offer terms it is to break them: they keep no faith with enemies: if you relax in your exertions, they persevere the more: if you make new efforts, they redouble theirs. While they give no quarter, you stand upon mere ceremony. While they are cutting your throat, or putting the gag in your mouth, you talk of nothing but liberality, freedom of inquiry, and douce humanité. Their object is to destroy you, your object is to spare them---to treat them according to your own fancied dignity. They have sense and spirit enough to take all advantages that will further their cause: you have pedantry and pusillanimity enough to undertake the defence of yours, in order to defeat it. It is the difference between the efficient and the inefficient; and this again resolves itself into the difference between a speculative proposition and a practical interest.
