"Critique of Judgment" by Immanuel Kant,1790

..
Judgment in general is the faculty of thinking the particular as contained under the universal ; if a judgment brings the particular under a given universal,it is determinant,and if it discovers a universal by which to judge a given particular,it is reflective.
.
Taste is the faculty of judging an object by a satisfaction (or dissatisfaction) which is not dependent on any quality of the object itself ;
the satisfaction is a subjective response to the mere representation of the object ;
hence,it is disinterested.
.
Even though beauty is subjective,it is universal ;
the beautiful is that which pleases universally because it satisfies the will as if it served a purpose.
.
The sublime is found when a formless object is represented as boundless,
even though its totality is present in thought.

"Critique of practical reason" by Immanuel Kant,1788

..
Morality can claim objectivity and universality only by being founded on pure reason itself.
.
Moral laws are universal and categorical because of their form,not their empirical content.
.
The fundamental law of the pure practical reason is so to act that the maxim of the will could always function as a principle establishing universal law.
.
Were it not for the moral law,man could never know himself to be free ;
for man,"thou ought" implies "thou canst".
.
The rational postulates of the practical reason are that man is free,that the soul is immortal,and that God exists.

"Critique of pure reason" by Immanuel Kant,1781

..
To establish the possibility of metaphysics as a science,it must be shown that synthesis a priori truths are possible.
.
Synthetic a priori truths are universally and necessarily true -hence a priori-,but their necessity cannot be derived by analysis of the meanings of such truths -hence,they are synthetic-.
.
The two sources of knowledge are sensibility and understanding.
.
Space and time are the priori forms of sensibility -intuition- ;
we are so constituted that we cannot perceive anything at all except by casting it into the forms of space and time.
.
The a priori conditions of our understanding are called the categories of our understanding : the categories
of quantity are unity,plurality,and totality ;
of quality : reality,negation,and limitation ;
of relation : substance and accident,cause and effect,and reciprocity between agent and patient ;
of modality : possibility-impossibility,existence-unexistence,and necessity-contingency.
.
The principles of science which serve as presuppositions are synthetic a priori ;
the possibility of such principles is based upon the use of a priori forms of intuition together with the categories of the understanding.
