A thought experiment used to criticize this theory considers an unemployed chemist named George. The“average” version of this theory is subject to Parfit’s mere addition paradox. A two-level version of this theory created by R. M. Hare posits a threshold of critical thinking to switch between its “act” and “rule” forms. One (10[1])advocate of this theory wrote An Introduction to the Principles of Morals and Legislation, which described a felicific calculus in (10[1])which intensity and duration of pleasure is considered. For (10[1])10 points, name this ethical philosophy advocated by Jeremy Bentham and (10[1])John Stuart (10[1])Mill, which (10[1])emphasizes the greatest good for the greatest number. ■END■
