Having read many biographies and autobiographies, I have concluded it is harder to write anautobiographythanabiography. Forwhen onewritesone’sownautobiography, oneis sorely temptedtoaggrandizeoneselfbyinflating one’sownachievementsand downplaying one’sown shortcomings. Howsoever selective, oneis also easily tempted to writefartoo much –and also tempted to flatter oneself; or, alternatively, to put oneself down.
On the other hand, biographers writing about other people — often betray their own bias. Too, they cannot possibly see the whole of the life of the person they are writing about — from the perspective of the person concerned. (Whatever that might be worth!)
