We can observe in the progression of the work of Thomas Hobbes through David Hume to John Rawls a development from a focus on severe disorder to order under law and then to concern with distribution. This striking development is not due simply to changes of normative views, but is in large part about the technical or virtually technological capacities of government. There are also non-normative theoretical and significant developments in their theories. Hence, much of the difference between these philosophers, (...) who superficially appear to disagree deeply, is essentially social scientific. If so, they should all be willing to revise conclusions to fit better social science. This is not the whole story, perhaps, or if it is, then we have to conclude that all of them make big scientific mistakes that vitiate their theories. On this view, Hume comes closest to having the theory right in his time and his account is more compelling as a social scientific account of our issues than are the accounts of Hobbes or Rawls.
