How to recognize a good leader?

Being-authority is grounded not only in the individual's competence to fulfill certain social functions, but equally so in the very essence of a personality that has achieved a high degree of growth and integration. Such persons radiate authority and do not have to give orders, threaten, bribe. They are highly developed individuals who demonstrate by what they are - and not mainly by what they do or say - what human beings can be.

--Erich Fromm
