  Later enlightenment thinkers reprise Spinoza’s claim that whereas the freedoms of thought and expression should be protected, one ought to obey the sovereign’s decisions on matters of action (TTP 20, 251–2). Echoes of this view may be found in Moses Mendelssohn’s separation of action and conviction in Jerusalem (Mendelssohn 1983, 40; Gottlieb 2011, 50), a work for which one scholar maintains that the TTP “serves, if not as model, at least as decisive subtext” (Goetschel 2004, 168). This division was even adopted by Frederick the Great, whose policy that men may argue about whatever they wish, provided that they obey is famously celebrated in Kant’s essay “What is Enlightenment?” [Was ist Aufklärung?].
