YOU must mix some uncertainty
With faith, if you would have faith be.
IF you will believe only in the perceptions of sense and distrust the intimations of the spirit, it is a question how low you will descend for your lest of certainty. Will you depend upon your own faculties in proportion as they are simply animal, and deny them in proportion as they are divine?— Confide in your eyesight and give the lie to the conscience and affections?
NEVER be afraid to doubt, if only you have the disposition to believe, and doubt in order that you may end in believing in Truth.
Samuel Tavlor Coleridge
