Secrecy is the soul of all great designs.

Duke Chartres used to boast that no man could have less real value for character than himself, yet he would gladly give twenty thousand pounds for a good one, because he could immediately make double that sum by means of it.

The blindness of bigotry, the madness of ambition, and the miscalculations of diplomacy seek their victims principally amongst the innocent and the unoffending. The cottage is sure to suffer for every error of the court, the cabinet, or the camp. When error sits in the seat of power and of authority, and is generated in high places, it may be compared to that torrent which originates indeed in the mountain, but commits its devastation in the vale.

The highest knowledge can be nothing more than the shortest and clearest road to truth; all the rest is pretension, not performance, mere verbiage and grandiloquence, from which we can learn nothing.

It is far better to borrow experience than to buy it.

Nothing more completely baffles one who is full of trick and duplicity than straigthforward and simple integrity in another. A knave would rather quarrel with a brother knave than with a fool, but he would rather avoid a quarrel with one honest man than with both. He can combat a fool by management and address, and he can conquer a knave by temptations. But the honest man is neither to be bamboozled nor bribed.

Total freedom from error is what none of us will allow to our neighbors; however we may be inclined to flirt a little with such spotless perfection ourselves.
