Skepticism, like chastity, should not be relinquished too readily.

-- George Santayana

What we especially like about Santayana's sentiment is its lack of absolutism.  It doesn't insist that under no circumstances should skepticism - or chastity - be abandoned.  Rather, it implies there should be a significant even compelling, reason for relinquishing either.
