In his monumental Critique of Pure Reason, German philosopher Immanuel
Kant (1724-1804) argues that human knowledge is limited by the capacity
for perception. He attempts a logical designation of two varieties of
knowledge: a posteriori, the knowledge acquired through experience;
and a priori, knowledge not derived through experience. Kant maintains
that the most practical forms of human knowledge employ the a priori
judgments that are possible only when the mind determines the conditions
of its own experience. This accurate translation by J. M. Meiklejohn
offers a simple and direct rendering of Kant's work that is suitable for
readers at all levels.
