Cherish your doubts, for doubt is the handmaiden of truth.Doubt is the key to the door of knowledge; it is the servant of discovery.A belief which may not be questioned binds us to error,for there is incompleteness and imperfection in every belief.Doubt is the touchstone of truth; it is an acid which eats away the false.Let no man fear for the truth, that doubt may consume it;for doubt is a testing of belief.The truth stands boldly and unafraid; it is not shaken by the testing;For truth, if it be truth, arises from each testing stronger, more secure.He that would silence doubt is filled with fear;the house of his spirit is built on shifting sands.But he that fears no doubt, and knows its use, is founded on a rock.He shall walk in the light of growing knowledge;the work of his hands shall endure.Therefore let us not fear doubt, but let us rejoice in its help:It is to the wise as a staff to the blind; doubt is the handmaiden of truth.
