A mature person is one who does not think only in absolutes,

A mature person is one who does not think only in absolutes, who is able
to be objective even when deeply stirred emotionally, who has learned
that there is both good and bad in all people and in all things, and who
walks humbly and deals charitably with the circumstances of life,
knowing that in this world no one is all-knowing and therefore all of us
need both love and charity.
-- Eleanor Roosevelt
