Abstract: The Advanced Introduction to Freedom of Expression provides an overview of major issues in the doctrinal structure of a law of freedom of expression, relevant to discussions of freedom of expression under many national constitutions. Assuming familiarity with basic theories of free expression, this book addresses the implications of reasonable disagreement between legislatures and courts about whether a specific measure violates freedom of expression, the implications of the fundamental proposition that speech can cause harm, the distinction between the coverage of freedom of expression and the protections it affords, and the appropriate doctrinal forms when speech is said to conflict with other rights such as equality, or merely other social interests. The book will be of interest to anyone, including students, teachers, researchers and policymakers wanting to learn more about the freedom of expression and the law.
