This is a 3-lecture course. Here's the synopsis from Craig Biddle's website:
The Science of Selfishness
This course demonstrates that ethics, like physics, is scientific through and through - that its principles are observation-based, logical, and absolute - and that if one grasps and applies them, one can achieve and maintain a life of profound happiness. The course examines, concretizes, and clarifies the principles of selfishness, showing their connection to perceptual reality, emphasizing their life-serving purpose, demonstrating their interrelationships, discussing their proper applications, and offering techniques for incorporating them into one's daily life. Topics include: the nature and essential criteria of science, Ayn Rand's scientific approach to ethics, the purpose of morality, the derivation and meaning of the principle that man's life is the standard of moral value, the principles of selfishness (including the "math" of egoism), and the art (or applied science) of selfishness. Egoists of all levels of knowledge will expand their understanding of the science of selfishness and thus of how to achieve a life of happiness.
