Abstract
It is widely acknowledged that Isaiah Berlin’s seminal essay “Two Concepts of Liberty” has to a large extent set the tone and determined the content of the debates within political philosophy in the English-speaking world. Berlin maintains that the conceptual and institutional history of liberty can be understood in terms of the various responses to the logically distinct questions: “Who governs me?” and “How far does government interfere with me?”. In Berlin’s first question, the salient issue is whether the valid authority to positively rule an individual resides within the individual herself or in some external person, social class, institution, empirical circumstance, or tradition. In contrast with the personal freedom to direct oneself, the second issue is concerned with liberating the individual from the coercion of others, especially the government, by limiting authority as such. Berlin dedicates much of his essay to demonstrating that the positive and negative concepts of liberty are not merely two sides of the same coin; rather, he argues that in human psychology and history these mark “two profoundly divergent and irreconcilable attitudes to the ends of life”. According to Berlin’s line of reasoning, to perceive the personal authority to rule oneself as one’s primary end requires a sacrifice of one’s negative liberty. Reciprocally, to make the limitation of authority and coercion in general one’s highest end demands that one relinquish some positive freedom.
