The answer doubtless lies in Hobbes' unsavory fame.

The man who made the Church a mere department of the State and justified not less the title of Cromwell than of the Stuarts was not the opponent for one who had a very practical problem in hand.

And Locke could answer that he was answering Hobbes implicitly in the second _Treatise_.

And though Filmer might never have been known had not Locke thus honored him by retort, he doubtless symbolized what many a nobleman's chaplain preached to his master's dependents at family prayers.
The _Second Treatise_ goes to the root of the matter.

Why does political power, "a Right of making Laws and Penalties of Death and consequently all less Penalties," exist?
It can only be for the public benefit, and our enquiry is thus a study of the grounds of political obedience.
