This book offers a systematic overview of major business ethics topics grounded in neo-Aristotelian virtue ethics and New Natural Law. Its broad approach spans philosophical themes to the most applied topics to promote business relations that respond to justice and responsibility. It presents business ethics as a theory of justice and the common good, offering a structured framework that integrates organizational, commercial, and corporate practices, consistently linked to the pursuit of excellence and human flourishing. This book is useful for philosophy professors who teach business and professional ethics courses, as well as graduate and undergraduate students in these courses. It is relevant to researchers interested in the ethical dimensions of business and management practice, especially those that touch on other management areas like strategy, marketing, or human resource management.
