the purity of morals, for the proper and inestimable worth of an
absolutely good will consists just in this, that the principle of

* To behold virtue in her proper form is nothing else but to
contemplate morality stripped of all admixture of sensible things
and of every spurious ornament of reward or self-love. How much she
then eclipses everything else that appears charming to the affections,
every one may readily perceive with the least exertion of his

The question then is this: "Is it a necessary law for all rational
beings that they should always judge of their actions by maxims of
which they can themselves will that they should serve as universal

with the very conception of the will of a rational being generally.
But in order to discover this connexion we must, however
