H. P. Grice's Principle of Conversational Beneficence

H. P. Grice’s principle of conversational beneficence -- beneficence Ethics [from Latin bene, well or good + facio, to do] Literally doing something to promote the good or interest of somebody else, due to a benevolent character. The word “benefit” comes from the same root. Beneficence is to act in a way that benefits others, and it is supplemented by non-maleficence [from Latin male, bad + facio, to do], that is, doing no harm. Beneficence has been recognized as a basic obligation or duty. To deal with possible conflicts between the principle of beneficence and other duties, such as the respect for autonomy, is a major topic in various areas of applied ethics. “[I]t must be remembered that ‘duty of beneficence’ means an obligation to do good to others.” Nowell-Smith, Ethics
