The Critique of Practical Reason

Kant · en
However, as it is still pure reason, the knowledge of which is
here the foundation of its practical employment, the general outline
of the classification of a critique of practical reason must be
arranged in accordance with that of the speculative. We must, then,
have the Elements and the Methodology of it; and in the former an
Analytic as the rule of truth, and a Dialectic as the exposition and
dissolution of the illusion in the judgements of practical reason. But
the order in the subdivision of the Analytic will be the reverse of
that in the critique of the pure speculative reason. For, in the
present case, we shall commence with the principles and proceed to the
concepts, and only then, if possible, to the senses; whereas in the
case of the speculative reason we began with the senses and had to end
with the principles. The reason of this lies again in this: that now
we have to do with a will, and have to consider reason, not in its
relation to objects, but to this will and its causality. We must,
then, begin with the principles of a causality not empirically
conditioned, after which the attempt can be made to establish our
notions of the determining grounds of such a will, of their
application to objects, and finally to the subject and its sense
faculty. We necessarily begin with the law of causality from
freedom, that is, with a pure practical principle, and this determines
the objects to which alone it can be applied.

                    I. DEFINITION.



Practical principles are propositions which contain a general
determination of the will, having under it several practical rules.
They are subjective, or maxims, when the condition is regarded by
the subject as valid only for his own will, but are objective, or
practical laws, when the condition is recognized as objective, that
is, valid for the will of every rational being.
