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."
Welfarism Welfarism is a form of consequentialism. Like all forms of consequentialism, welfarism is based on the premise that actions, policies, and/or rules should be evaluated on the basis of their consequences. Welfarism is the view that the morally significant consequences are impacts on human (or animal) welfare. There are many different understandings of human welfare, but the term "welfarism" is usually associated with the economic conception of welfare. Economists usually think of individual welfare in terms of utility functions, a perspective in which social welfare can be conceived as an aggregation of individual utilities or utility functions.
