Immanuel Kant's Crtique of Pure Reason is a work of genius and is widely regarded by acadmic philosophers as one of the most important philosophical texts ever written. Kant's aim in this work was to synthesise the doctrines of the rationalist and empirical schools, which had dominated philosophy for over a hundered years, by describing the limits of human knowledge. This was a moumental task but Kant rose to the challenge and produced a masterpiece. However, as important and revolutionary as this work undoubtely is, it is not for the faint hearterd. It is an extremly difficult book to read and Kant makes use of a great deal of technical jargon which will cause problems to the uninitiated. As a result, I would highly recommend buying an introductory book on Kant before attemtping to read this work. But when you do get around to reading it you will find that it is well worth the effort for this, as I say, is a work of genius!
