Psychological research on courage has developed from the philosophical understanding of courage as a virtue into an interdisciplinary investigation of how people voluntarily confront danger, fear, uncertainty, or social opposition in pursuit of significant goals. Contemporary researchers generally distinguish physical courage, involving bodily danger; moral courage, involving the defence of ethical principles despite potential personal or social costs; and psychological courage, involving the confrontation of distress, vulnerability, or deeply personal challenges (Pury & Lopez, 2010; Pury, 2017).
An important early contribution came from Stanley Rachman (1984), whose investigations of fear and courage, including work involving military bomb-disposal personnel, distinguished courage from fearlessness and suggested that courageous action can occur in the presence of substantial fear. His later work further explored the psychological mechanisms underlying courageous behaviour (Rachman, 2010). Christopher R. Rate, Jennifer A. Clarke, Douglas R. Lindsay, and Robert J. Sternberg (2007) investigated people's implicit theories of courage and identified recurring features of courageous action: intentionality, deliberation, substantial risk, a worthy or noble purpose, and action despite fear. Their findings helped establish a more systematic conceptual framework for subsequent empirical research (Rate et al., 2007).
Cynthia L. S. Pury and Shane J. Lopez (2010) brought together research on courage as a goal-directed action involving personal risk, examining the roles of emotion, values, self-regulation, social influence, altruism, and efficacy. Their work also highlighted the importance of distinguishing courageous behaviour itself from the retrospective recognition or praise of a person as courageous. Research on measurement has likewise challenged the assumption that fear must always be present:
Christopher R. Woodard and Cynthia L. S. Pury (2007) developed the Woodard–Pury Courage Scale-23, identifying several context-dependent dimensions of courage, including workplace, social-moral, and family-related situations. More recent research has extended the field into organisational behaviour, healthcare, leadership, and social justice, while emphasising that courage must be evaluated in relation to the purpose pursued, since risk-taking is not necessarily virtuous merely because it is bold (Pury et al., 2015; Detert & Bruno, 2017).
From a Christian perspective, courage is not simply fear suppression or individual heroism but faithful action grounded in trust in God, love of neighbour, and commitment to the good. Joshua 1:9 links courage with God's presence, Psalm 27:1–3 presents confidence in God amid danger, and John 15:13 associates the greatest love with laying down one's life for one's friends. The Apostle Paul similarly urges believers to stand firm in faith and act in love (1 Corinthians 16:13–14), while Christ's obedience and endurance in Gethsemane (Matthew 26:36–46) illustrate that fidelity can coexist with anguish rather than require emotional fearlessness.
From an Eastern Orthodox theological perspective, courage can be understood within the cultivation of the virtues and the process of theosis – participation by grace in the life of God (2 Peter 1:4) – rather than as self-sufficient willpower. In the classical account of St Maximus the Confessor, the virtues are integrated into the healing and transformation of the human person through cooperation with divine grace. Courage therefore serves love and discernment rather than pride or aggression. St John Climacus, in The Ladder of Divine Ascent, similarly presents spiritual perseverance as part of the struggle against the passions and the growth of humility. Orthodox spirituality thus complements psychological accounts by locating courage in faithful endurance, compassionate action, repentance, and hope, while insisting that authentic courage requires discernment: suffering, confrontation, or risk is not automatically holy, and the courageous response is the one directed towards truth, love, and communion with God and neighbour.
