Only a small fraction of students today receive any direct training in logic or critical thinking — and most of what remains is a truncated, centuries-old version of Aristotelian logic. At the same time, the ability to produce images, audio, and video that are practically indistinguishable from reality has never been more accessible. The ability to discern truth from what's right in front of us has never mattered more, or been less common.

For the Love of Truth teaches Philalethic Logic: a thorough reasoning system that is quantified, compound, modal, and symbolic — and, above all, practical. It's grounded in how the human mind actually works, rather than treated as a purely abstract exercise. It uses a simplified, intuitive symbolic grammar. It takes compound operators like disjunction and implication seriously in their full modal sense, resolving confusions that plague more conventional systems. And it relies on one consistent validation method — truth-tree decomposition — carried all the way through, rather than switching techniques chapter to chapter.

The project is built around three coordinated resources: the main text itself, a Teacher & Parent Supplement for anyone teaching it who hasn't necessarily studied formal logic before, and a Student Workbook of additional practice labs for independent study. A live weekly class is also available through Family Membership for anyone who'd like to learn alongside an instructor.

About Seth Murray

Seth Murray was first exposed to the fundamentals of mathematical logic around 1981 as he learned basic computer programming on the Commodore VIC-20. Since then, he completed degrees in physics and engineering science, philosophy, and theology, and has done doctoral-level study in physics, counseling, and humanities and philosophy. He has trained in philosophical counseling and is certified in logic based therapy. He married in 1991, has seven children, and four grandchildren. He has taught philosophy, theology, Scripture, history, and science for many institutions, including churches, private high school academies, and colleges. He is now a priest and pastor at a small mission chapel in Oregon. He is passionate about the pursuit of truth, unity, and peace. He enjoys martial arts, especially jiu jitsu, spending time with his wife and family, fixing things, and engaging in various creative projects.
