Paul Gottfried argues that what separates Left from Right is not equality vs liberty but equality vs inequality. Thomas Sowell argues that the difference is a constrained vision vs an unconstrained vision of humanity, human society, human potential, and so forth. Others have argued the difference is one of universalism vs particularism, or a linear view of history vs the view that history is either cyclical or simply a series of events with no discernible pattern. Still others say the difference is one of tradition vs the experimental. So which one is it, or is it all of these?
