Most of us try to act ethically, drawing our standards from our social upbringing (The Ethic of Community), from our religions (The Ethic of Divinity), or from our own personal reasoning (The Ethic of Autonomy), but we don't always agree on what's right. In this pithy book that combines social commentary with both philosophy and psychology, Tony Annesi suggests that even if we cannot always bridge the gaps between our ethics, we can use both reason and rational self-interest to evaluate them.
