The book "Justifying Intellectual Property" by Robert P. Merges explores the idea that creators should have strong rights to control who can use their work. By focusing on the creator, the book aims to benefit professional creators. Merges discusses philosophers like Locke, Kant, and Rawls to support his arguments. The book suggests that giving creators more control over their work can solve some issues with the current intellectual property system, even though it may challenge the system's current power.
