Does everyone have a basic need to know the truth of their origins?

Can an individual who doesn't instinctively understand about the need for everyone to know his or her true and original identity be made to change his mind?

I don't know. After a conversation I had the other night it seems unlikely--unlikely at least that a non-adopted person can move the heart and mind of anyone who knows an adoptee who professes no need to know, and is, for all the world to see, a well adjusted, successful, happy individual. But I cannot help think this: Since curiosity is the sign of intelligent life, how can an otherwise intelligent person not be interested in the story of his own life?
