The article explores the concept of egoism in ethics, including simple desire egoism and a revised form that considers longer-term interests. It examines counterarguments raised by Socrates against Callicles' egoistic principle and how they can be addressed using the revised form of egoism. The article argues that the best life is not one where you get what you want immediately, but rather one where you secure your long-term interests. However, this definition raises questions about an external standard for determining one's will, which Callicles and Nietzsche reject. The article also compares Plato's views on egoism with those of Callicles and Thrasymachus, and how he differs from hedonism, which advocates for gratification and pleasure as the ultimate values in life.
