Few philosophers stand out as boldly as Immanuel Kant. While he did not write as much as others, his principle works, Critique of Pure Reason, Critique of Practical Reason, and Critique of Judgment, are known worldwide. During his time, schools of Kantianism quickly sprang up and were later joined by schools of Neokantianism. Admittedly, not all of Kant's concepts have aged well, but many are still taught among the basics of philosophy today and therefore must be known by every student.

The A to Z of Kant and Kantianism provides a comprehensive dictionary that will aid not only students, but also teachers and the general public, since it contains hundreds of entries describing Kant's life and works, and explaining his concepts as well as the contributions of his followers (and also some opponents). Furthermore, much of the writings of the Neokantians, as well as the literature dealing with this movement, are not available in English, thus, this book provides an introduction to this phenomenon to the English-language reader. Given the inevitable problems of language, the glossary is particularly helpful, while the bibliography makes the massive amounts of literature more accessible.
