  In the realm of politics, Hume again takes up an intermediate position. He objects both to the doctrine that a subject must passively obey his government no matter how tyrannical it is and to the Lockean thesis that citizens have a natural right to revolution whenever their rulers violate their contractual commitments to the people. He famously criticizes the notion that all political duties arise from an implicit contract that binds later generations who were not party to the original explicit agreement. Hume maintains that the duty to obey one’s government has an independent origin that parallels that of promissory obligation: both are invented to enable people to live together successfully. On his view, human beings can create a society without government, ordered by conventional rules of ownership, transfer of property by consent, and promise-keeping. We superimpose government on such a pre-civil society when it grows large and prosperous; only then do we need to use political power to enforce these rules of justice in order to preserve social cooperation. So the duty of allegiance to government, far from depending on the duty to fulfill promises, provides needed assurance that promises of all sorts will be kept. The duty to submit to our rulers comes into being because reliable submission is necessary to preserve order. Particular governments are legitimate because of their usefulness in preserving society, not because those who wield power were chosen by God or received promises of obedience from the people. In a long-established civil society, whatever ruler or type of government happens to be in place and successfully maintaining order and justice is legitimate, and is owed allegiance. However, there is some legitimate recourse for victims of tyranny: the people may rightly overthrow any government that is so oppressive as not to provide the benefits (peace and security from injustice) for which governments are formed. In his political essays Hume certainly advocates the sort of constitution that protects the people’s liberties, but he justifies it not based on individual natural rights or contractual obligations but based on the greater long-range good of society.
