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.
-Robert T. Weston, from Hymns for the Celebration of Life
