David Hume (1711-1776) proposed that determinism and "liberty" are compatible.  It has been a failure to define "liberty" clearly enough that has stood in the way of agreement on the topic.  We interpret all of reality as a pattern of causes and their effects.  What we really see is an unvarying sequence of events.  But we humans have the mental habit of inferring cause and effect relations.  We interpret all physical events as the product of such relations.  We should recognize that we also interpret all human behavior along the same lines.  Hume discusses at length the predictability of human behavior.  Acknowledging endless variants and surprises n behavior, we nonetheless constantly think that people act in accord with their character, their passions, their desires, their motives -- that they have reasons for what they do.  The alternative is to suppose that people at least sometimes act for no reason whatsoever.  But if that is ever so, in those cases there is no human choice at work and no responsibility.  So that does not save human liberty; instead it replaces it with chaos.
     Benson discussed this partly in terms of "Benson's rebellion."  This is a hypothetical case of Benson acting contrary to his character, acting unpredictably.  Yet even here, according to Hume, Benson had motives, reasons, for this rebellion.  So this act of liberty was nonetheless determined  by those motives and reasons.
     In the end Hume redefines "liberty" to mean only "absence of constraint," so that when a person decides to do something, as determined by the sum of all the causes at work including the person's motives and habits, the person is able to carry out that decision.  (Benson speculated on what Hume would say about conditions like those in the novel Brave New World, in which people were free to act on their decisions, but in a context where they were programmed to make only certain kinds of decisions.)
