Who carries doubtful people to his house, will doubtless from his carriage something lose.
When in doubt, surprise them.
When in doubt of what is right, consult your pillow overnight.
The believer is happy; the doubter is wise.
Quiet people, whether wise or dull, get the benefit of the doubt.
Never try to prove what nobody doubts.
If there is still doubt do not accuse.
He who trusts is happy; the doubter is wise.
He who knows nothing neither doubts nor fears anything.
