Ethics is the study of the nature of proper choice and conduct. In situations which only affect oneself, Scionics applies the principle of empiricorational hedonism: the guiltless, empiricorational pursuit of maximum hedonic value. (Positive hedonic value leads to an increase in pleasure or a decrease in pain, and negative hedonic value leads to a decrease in pleasure or and increase in pain.) In situations which involve others, the hedonic principle is further integrated with the non-aggression principle: the recognition that no individual or group of individuals may ethically initiate force, fraud or coercion against another. The integration of empiricorational hedonism and the non-aggression principle results in the the principle of non-aggressive empiricorational hedonism: the guiltless, empiricorational and non-aggressive pursuit of maximum hedonic value.
