How to use this curriculum

Study them in this exact order to develop a clear and coherent understanding of ethics (before moving to Advanced Topics):

  1. Philosophical Orientation and Tools
    Start here. This section teaches you how to think philosophically and how to read, analyze, and evaluate arguments — skills you will use in every later section.

  2. Historical Foundations of Ethical Thought
    Next, work through the historical development of major ethical ideas. This gives you the big picture of how moral philosophy has evolved over time.

  3. Core Ethical Theories (Normative Ethics)
    This is the heart of the subject. Here you learn the three major families of ethical theories that almost every contemporary ethical discussion still relies on.

  4. Metaethics
    Finish the core by studying metaethics. This section helps you understand what moral claims actually mean and whether they can be objectively true — the deepest “why” questions behind the theories you just learned.
