In “The Art of Loving”, Erich Fromm explores the nature of love in various forms, including romantic, brotherly, and self-love. He argues that love is an art that requires knowledge, effort, and practice rather than a passive or spontaneous emotion. Fromm emphasizes the importance of overcoming narcissism and developing a mature, productive love that involves care, responsibility, respect, and knowledge. The book provides deep psychological insights and practical advice on cultivating and sustaining meaningful and fulfilling relationships.
