The course first examines different concepts of freedom, such as negative liberty and positive liberty, and then reflects on the significance of fundamental freedom like freedom of speech. It will then address the big question, "What acts may the state rightly make criminal?" We will discuss four liberty-limiting, or coercion-legitimizing, principles in this course even though the famous 19th century philosopher John Stuart Mill argues that the harm-to-others principle is the only legitimate liberty-limiting principle. The other principles that we will discuss are: (1) the offense principle: it is necessary to prevent hurt or offence (as opposed to harm) to others; (2) legal paternalism: it is necessary to prevent harm to the actor herself; and (3) legal moralism: it is necessary to prevent immoral conduct whether or not it harms anyone. Relevant case studies will be conducted for each of these four principles.
