Prudence operates on life in the same manner as rule of composition; it produces vigilance rather than elevation; rather prevents loss than procures advantage; and often miscarriages, but seldom reaches either power or honor. – Samuel Johnson
I consider it a mark of great prudence in a man to abstain from threats or any contemptuous expressions, for neither of these weaken the enemy, but threats make him more cautious, and the other excites his hatred, and a desire to revenge himself. – Niccolo Machiavelli
The instruction we find in books is like fire. We fetch it from our neighbours, kindle it at home, communicate it to others, and it becomes the property of all. – Voltaire
