No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
I have had, and may have still, a thousand friends, as they are called, in life, who are like one's partners in the waltz of this world -not much remembered when the ball is over.
If friends disappoint you over and over, that's in large part your own fault. Once someone has shown a tendency to be self-centered, you need to recognize that and take care of yourself; people aren't going to change simply because you want them to.
He that wrongs a friend Wrongs himself more, and ever bears about A silent court of justice in his breast, Himself the judge and jury, and himself The prisoner at the bar ever condemned.
It is not merely true that a creed unites men. Nay, a difference of creed unites men - so long as it is a clear difference. A boundary unites. Many a magnanimous Moslem and chivalrous Crusader must have been nearer to each other, because they were both dogmatists, than any two agnostics. "I say God is One," and "I say God is One but also Three," that is the beginning of a good quarrelsome, manly friendship.
To give and receive advice - the former with freedom, and yet without bitterness, the latter with patience and without irritation - is peculiarly appropriate to geniune friendship.
A friend is a person with whom I may be sincere. Before him I may think aloud. I am arrived at last in the presence of a man so real and equal, that I may drop even those undermost garments of dissimulation, courtesy, and second thought, which men never put off, and may deal with him with the simplicity and wholeness with which one chemical atom meets another.
