Iqbal's theory of personality development involves several key elements. It proposes that an ideal society for developing strong personalities would be based on spiritual principles like monotheism, have inspired leadership, a moral code to guide society, and clear collective goals. Within such a society, personality develops through stages of obeying God, attaining self-control, and fulfilling humanity's role as God's steward. Strong personalities are strengthened by virtues like love, asceticism, courage, tolerance, and lawful and creative work, while weaknesses develop from fear, dependency, slavery, and ancestral pride.
