Description

My latest book, The Power of Four: Elements, Humors, Temperaments, Types, is a sweeping history of four foundational concepts that have guided Western thought from the earliest days of Western civilization. Divided into four parts, the book takes an evolutionary stance, looking at how each concept—elements, humors, temperaments, and types—developed and then evolved into the next. 

It also leans heavily on the archetypal nature or "power" of four, both "fourness," as in four elements, humors, and temperaments, and "fourfoldness," as in 4 x 4 or 16 personality types. Although touching upon other numerological schemes related to personality theory, the text stays focused on the number four, the most prevalent concept upon which much of Western thought is built. 

The Power of Four is available as a paperback ($19.00) and as an e-book ($12.99) from many of your favorite online booksellers. You can also order a physical copy from your local bookstore as well. To purchase a copy online, please click HERE. 

Reviews

A thoughtful, accessible account of our persistent urge to organize complexity and ourselves into fours... Nikola-Lisa's conversational prose makes Greek cosmology, Galenic medicine, and personality theory unusually approachable.  Prairies Book Review (26 July 2026)

The Power of Four is a far-reaching, deeply researched, and meticulously referenced work that is filled with fascinating information and revealing insights. Nikola-Lisa's wonderfully approachable manner ensures that this entertaining and educationally valuable book deserves a wide audience. The Book Review Directory (15 July 2026)

The Power of Four is a book that intellectual historians, philosophy students, and lovers of ancient Greek thought will deeply approeciate. It is historically rich, and though dense in historical scope, chronological range, and conceptual depth, it will absolutely reward those who agree to sit with its complexity and engage with its ideas. How it brigns the past to life is truly masterful technique that creators and writers will love to borrow from, and maybe even apply in their work. Lastly, rare among books of its kind, it is a book that will leave readers rethinking the very frameworks they normally use to understand the world. Feathered Quill Reviews (19 June 2026)
