Charles Sanders Peirce Quotes about Doubt

We cannot begin with complete doubt.

Charles Sanders Peirce (1991). “Peirce on Signs: Writings on Semiotic”, p.55, UNC Press Books

Doubt is an uneasy and dissatisfied state from which we struggle to free ourselves and pass into the state of belief; while the latter is a calm and satisfactory state which we do not wish to avoid, or to change to a belief in anything else.
