This Philosophical Lexicon is an analytical glossary of terms whose understanding is indispensable for the serious study of literature and of literary traditions. As such, it leaves aside consideration of terms associated only with discrete historical periods or with merely conventional literary practices. Instead, it focuses on key terms that pertain to those fundamental features that are shared by all literary traditions, no matter when or where they may be found.

Further, rather than seeking to conform its explanation of these universally relevant terms to a predetermined schema, this Lexicon roots its definitions in the practical experience attentive readers have of literary works themselves. Thereby, it aims to show readers how to attain the deepest possible penetration of any individual work of art, helping them better apprehend its uniqueness as well as to appreciatre its value as a delightful object of beauty.
