Craig Biddle talks about the concepts contained in what he calls the Trinity of Liberty: individualism, individual rights and independent thinking. Individualism is the fundamental unit of moral and political concern; independent thinking is the virtue of demanding evidence for the ideas accepted; and individual rights are the prerogative to act free on one’s judgment in order to execute ideas within society. Each concept is taken into account, hierarchically, considering independent thinking to be the more fundamental. Biddle explains in detail the true meaning of these ideas and describes how they interact with one another. Finally, he concludes by illustrating the main goal of rational egoism and portrays the moral foundations and values it pursues.
