In this book Tibor R. Machan analyses the state of the debate on libertarianism post Nozick. Going far beyond the often cursory treatment of libertarianism in major books and other publications he examines closely the alternative non-Nozickian defences of libertarianism that have been advanced and, by applying these arguments to innumerable policy areas in the field, Machan achieves a new visibility and prominence for libertarianism.
