The science behind character strengths and human virtue
UBVirtuous2 is built upon the most comprehensive scientific classification of human character ever developed—the VIA Classification of Character Strengths and Virtues. This page provides a complete bibliography of the academic works, books, and research papers that inform the product's 6 core virtues, 24 character strengths, and 40 modules. Each source is available through Amazon with direct purchase links.
The foundational research upon which UBVirtuous2's structure is built:
2004 • Oxford University Press • 800 pages
The definitive scientific classification of human character that forms the backbone of UBVirtuous2. This landmark 800-page volume represents a 3-year, multi-million dollar collaboration involving 55 distinguished scientists. It identifies 24 character strengths organized under 6 universal virtues, validated across cultures and throughout history—often called "the Un-DSM" of psychology.
Essential texts from the founders and leaders of character strengths research:
2002 • Atria Books
The book that launched positive psychology into mainstream consciousness. Seligman introduces signature strengths and shows how identifying and using your top character strengths leads to authentic happiness—distinct from pleasure or engagement alone.
2011 • Atria Books
Seligman expands beyond happiness to comprehensive flourishing through PERMA: Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment. Character strengths serve as the pathways to achieving each element of wellbeing.
2018 • Hogrefe Publishing
The practical guide to applying VIA character strengths in real-world settings. Niemiec, Education Director at the VIA Institute, provides over 70 interventions and 340+ activity handouts for developing each of the 24 character strengths.
2019 • VIA Institute on Character
An accessible guide to understanding and applying all 24 character strengths. Includes research highlights, practical exercises, and "strength spotting" techniques for each strength, making the science actionable for everyday life.
Books that translate character science into daily practice:
2014 • Hogrefe Publishing
The integration of mindfulness meditation with character strengths development. Niemiec shows how mindful awareness enhances the cultivation and expression of all 24 VIA strengths—combining two evidence-based approaches to flourishing.
2006 • Oxford University Press
A comprehensive introduction to positive psychology from one of the VIA framework's co-creators. Peterson covers character strengths alongside other pillars of the field, providing academic rigor in accessible language.
2010 • Crown Business
Achor's research at Harvard shows how positive psychology principles, including signature strengths, drive success in professional settings. Practical strategies for leveraging character strengths in the workplace.

The VIA Classification draws on virtue traditions spanning millennia. These philosophical works inform the deep structure:
~340 BCE • Hackett Publishing
Aristotle's foundational work on virtue ethics—the philosophical basis for character strengths. Introduces eudaimonia (flourishing) achieved through the cultivation of virtues like courage, temperance, and practical wisdom.
~180 CE • Modern Library
The Stoic emperor's personal journal on virtue and character. Demonstrates practical wisdom, self-regulation, and courage in action—providing quotes that appear throughout UBVirtuous2's modules.
