"Anybody can become angry - that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way - that is not within everybody's power and is not easy."

"Anger is an acid that can do more harm to the vessel in which it is stored than to anything on which it is poured."

"Anger dwells only in the bosom of fools."

"Bitterness is like cancer. It eats upon the host. But anger is like fire. It burns it all clean."

"In a controversy the instant we feel anger we have already ceased striving for the truth, and have begun striving for ourselves."
