What British academic philosopher has this quote attributed to him regarding the principle of charity "it constrains the interpreter to maximize the truth or rationality in the subject's sayings."?
Principle of charity In philosophy and rhetoric, 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."
Social contract In both moral and political philosophy, the social contract or political contract is a theory or model, originating during the Age of Enlightenment, that typically addresses the questions of the origin of society and the legitimacy of the authority of the state over the individual. Social contract arguments typically posit that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority of the ruler or magistrate (or to the decision of a majority), in exchange for protection of their remaining rights. The question of the relation between natural and legal rights, therefore, is often an aspect of social contract theory. The term takes its name from "The Social Contract" ("Du contrat social ou Principes du droit politique"), a 1762 book by Jean-Jacques Rousseau that discussed this concept.
