The author
Kristian Fennessy
Kristian Fennessy writes the Stoic Fundamentals series — one foundational Stoic idea per book, taken in depth and sourced entirely to the original texts in the public domain.
The series grew out of a plain frustration: the most useful ideas in Stoicism are everywhere as quotes and almost nowhere as something you can actually use on a hard day. Each book takes a single idea and follows it all the way down, into the places it is easiest to quote and hardest to live.
He also writes Stoicism at Work, a companion series that brings the same ideas to working life.
The standard
The series is called the fundamentals, so its authority has to come from getting the philosophy right rather than from sounding new. That produces a few rules, and they are not negotiable.
Ideas are called what the tradition calls them — the dichotomy of control, the reserve clause, premeditatio malorum, amor fati — rather than renamed to sound fresh. No branded practices are invented. Every quotation comes from a public-domain translation, one locked edition per work, verified against that edition before it is printed. Where an idea reaches its limit, the book says so instead of overselling.
Vitality Press
Vitality Press publishes the series. Both series are written for a general reader who keeps hearing about Stoicism and wants to understand it properly, without a philosophy degree and without being sold anything mystical.
