If we submit everything to reason, our religion will have nothing in it mysterious or supernatural. If we violate the principles of reason, our religion will be absurd and ridiculous.

As the grand discordant harmony of the celestial bodies may be explained by the simple principles of gravity and impulse, so also in that more wonderful and complicated microcosm the heart of man, all the phenomena of morals are perhaps resolvable into one single principle, the pursuit of apparent good; for although customs universally vary, yet man in all climates and countries is essentially the same.

Not only are moral laws with their principles essentially distinguished from every other kind of practical knowledge in which there is anything empirical, but all moral philosophy rests wholly on its pure part. When applied to man, it does not borrow the least thing from the knowledge of man himself (anthropology), but gives laws a priori to him as a rational being. No doubt these laws require a judgment sharpened by experience, in order on the one hand to distinguish in what cases they are applicable, and on the other to procure for them access to the will of the man and effectual influence on conduct; since man is acted on by so many inclinations that, though capable of the idea of a practical pure reason, he is not so easily able to make it effective in concreto in his life.
