The principle of charity requires interpreting a speaker's statements to be rational and, in the case of any argument, considering its best, strongest possible interpretation. In its narrowest sense, the goal of this methodological principle is to avoid attributing irrationality, logical fallacies or falsehoods to the others' statements, when a coherent, rational interpretation of the statements is available. According to Simon Blackburn "it constrains the interpreter to maximize the truth or rationality in the subject's sayings."

Neil L. Wilson named the principle in 1958–59. Willard Van Orman Quine and Donald Davidson provide other formulations of the principle of charity.
