Whatever the number of a man's friends, there will be times in his life when he has one too few; but if he has only one enemy, he is lucky indeed if he has not one too many.
You can discover what your enemy fears most by observing the means he uses to frighten you.
Be assured those will be thy worst enemies, not to whom thou hast done evil, but who have done evil to thee. And those will be thy best friends, not to whom thou hast done good, but who have done good to thee.
If we could read the secret history of our enemies we should find in each man's life sorrow and suffering enough to disarm all hostility.
Whoever benefits his enemy with straightforward intention that man's enemies will soon fold their hands in devotion.
