Humanistic, Existential, and Positive Aspects of Personality focuses on the meaning of human existence. Existentialism argues that people cannot be defined by fixed laws and emphasizes subjective experience and personal responsibility. Key figures like Rogers, Maslow, and Frankl viewed people as inherently driven towards growth, self-actualization, and finding purpose and meaning. Positive psychology later emerged to scientifically study subjective well-being, happiness, and human flourishing.
