Abstract
Legal theorists discuss "the Harm Principle", but usually fail to distinguish two different principles: according to the "Harmful Conduct Principle", we have good reason to criminalise conduct if [and only if] that conduct wrongfully causes or risks causing harm to others; according to the "Harm Prevention Principle", we have good reason to criminalise conduct if [and only if] doing so will efficiently prevent harm to others. we show why it is important to distinguish the two principles, and how they generate two very different routes towards criminalisation.
