“Character is something you forge for yourself; temperament is something you are born with and can only slightly modify.”

“Confusing ‘Character’ with ‘Temperament’”
Clearing the Ground (1986)
Context: Character is something you forge for yourself; temperament is something you are born with and can only slightly modify. Some people have easy temperaments and weak characters; others have difficult temperaments and strong characters.
We are all prone to confuse the two in assessing people we associate with. Those with easy temperaments and weak characters are more likable than admirable; those with difficult temperaments and strong characters are more admirable than likable. Of course, the optimum for a person is to possess both an easy temperament and a strong character, but this is a rare combination, and few of us are that lucky. The people who get things done tend to be prickly, and the people we enjoy being with tend to be accepting, and there seems to be no way to get around this. Obviously, there are many combinations of character and temperament, in varying degrees, so that this is only a rough generalization — but I think it is one worth remembering when we make personal judgments.
