Character Strengths and Virtues: A Handbook and Classification

Christopher Peterson and Martin Seligman

In a sentence

This handbook provides a systematic classification and measurement of 24 widely-valued character strengths, organized under six core virtues, creating a 'manual of the sanities' to counterbalance psychology's traditional focus on disorder.

For decades, psychology has expertly mapped human weakness and disorder, but what about the other half of the human condition? 'Character Strengths and Virtues' represents a landmark achievement from the leaders of the positive psychology movement, offering the first comprehensive, scientifically-grounded classification of human goodness. Moving beyond armchair philosophy, Christopher Peterson and Martin Seligman identify 24 distinct character strengths—such as courage, kindness, creativity, and hope—and group them under six universal virtues found across cultures and throughout history: wisdom, courage, humanity, justice, temperance, and transcendence. Each strength is thoroughly explored, providing its definition, theoretical background, measurement strategies, correlates, and developmental trajectory. This book is not just a classification; it is a foundational text for a new science of human flourishing, providing the vocabulary and tools for researchers, clinicians, educators, and anyone interested in understanding, measuring, and cultivating the best in themselves and others.

The model

This model represents the framework from 'Character Strengths and Virtues,' which posits that 24 distinct character strengths are the psychological components of 6 universal virtues. The model suggests that enabling conditions and deliberate interventions can foster these strengths, and the exercise of these strengths, in turn, contributes to a variety of fulfillments and desirable life outcomes. The character strengths mediate the relationship between developmental/contextual factors and a flourishing life.

Run the assessment

The story

The reader A researcher, educator, clinician, or intellectually curious individual who is seeking a rigorous, scientific framework to understand, measure, and cultivate the positive aspects of human nature.

External problem

The field of psychology has historically focused on diagnosing and treating illness, providing a comprehensive manual for disorders (the DSM) but no equivalent 'manual of the sanities' for human strengths and virtues.

Internal problem

The reader feels frustrated and limited by the deficit-focused 'disease model,' sensing that it offers an incomplete and pessimistic view of the human condition, and they lack the tools to empirically study or foster well-being.

Philosophical problem

It is fundamentally wrong for a science dedicated to the human mind to neglect what makes life worth living, focusing on fixing what's broken while ignoring how to build what's strong.

The plan

  1. Learn the VIA (Values in Action) classification system of 6 universal virtues and 24 measurable character strengths.
  2. Read the detailed chapters on each of the 24 strengths to understand their scientific basis, measurement, and development.
  3. Utilize the assessment strategies discussed, such as the VIA Inventory of Strengths (VIA-IS), to begin identifying and measuring strengths in yourself and others.

Success

  • The reader possesses a scientific vocabulary and a toolkit for understanding, measuring, and cultivating human flourishing.
  • They can apply this knowledge in research, clinical practice, education, or their own lives to foster character strengths.
  • Life is seen not just as the absence of problems, but as the presence of virtues and the pursuit of a meaningful, engaged, and fulfilling existence.

At stake

  • The reader remains confined to a problem-focused view of human nature, lacking a systematic framework for understanding or promoting well-being.
  • The conversation about character and virtue stays in the realm of rhetoric and opinion, without a scientific foundation.
  • The potential for a comprehensive psychology, one that addresses both human weakness and human strength, remains unrealized.

Questions this book answers

What is character, and can it be broken down into distinct, measurable components?
Are there universal virtues and character strengths that are valued across all cultures and historical periods?
How can we scientifically classify and measure positive traits, creating a counterpart to the Diagnostic and Statistical Manual of Mental Disorders (DSM)?
What are the causes, correlates, consequences, and developmental trajectories of specific character strengths like creativity, bravery, kindness, and hope?
How can good character be deliberately cultivated in individuals, schools, and communities?
