There is at least something in common: namely, the point of departure found in a 'hypothesis' or proposition of consciousness affected by a coefficient of uncertainty (as with Cartesian doubt) and the point of arrival found in an eminently moral apodicticity or imperative (Plato's One Good, the non deceiving God of the Cartesian Cogito, Leibniz's principle of the best of all possible worlds, Kant's categorical imperative, Fichte's Self, Hegel's 'Science').
