What is love?
Executive summary
Love is a cluster concept—an array of related but distinct phenomena that philosophers divide into types such as eros (passionate desire), philia (friendship), and agape (unconditional or altruistic love) rather than a single uniform thing [1]. Contemporary accounts add layers—psychological, evolutionary, and practice‑based perspectives—that disagree about whether love is primarily feeling, choice, biology, or moral practice [2] [3] [4].
1. Love as a family of concepts: eros, philia, agape and more
Classical sources and modern surveys insist that “love” names several different states and relationships, not one essence: eros as erotic desire, philia as friendship or comradeship, and agape as self‑giving or divine love are recurring taxonomies; later lists expand to include storge (familial), pragma (practical committed love), ludus (playful), and mania (obsessive) [1] [5] [6]. Philosophical treatments use these distinctions to explain why “I love chocolate” and “I love my partner” are the same word but different phenomena, and to parse puzzles about justification, value, and autonomy in love [1] [2].
2. Competing theories: feeling, biology, practice, and vision
Three broad theoretical families compete: reductionist accounts treat love as emotion or neural chemistry—an evolved bonding mechanism that aids reproduction and social cohesion [3]; intellectualist or vision views emphasize love as a way of seeing the beloved that transforms perception and value [7]; and practice‑based views argue love is enacted commitment and skill, neither mere feeling nor pure choice but a set of practices and standards that produce and sustain love [4] [8]. Each account captures part of the phenomenon but also attracts critiques: biological readings can flatten moral dimensions, vision views can seem elitist, and practice theories risk downplaying involuntary attractions [3] [9] [4].
3. Moral and political dimensions: love isn’t just private
Philosophers trace love into ethics and politics: some, following Aristotle and Aquinas, define loving as willing the good of another, making love a moral orientation [6], while others worry that love can justify partiality that conflicts with justice or that ideologies repurpose “love” to police behavior or market products [2] [7]. Debates continue over whether love’s value is intrinsic, instrumental, or both, and whether love enhances autonomy or can undermine it by creating dependency—questions central to ethical assessments [1] [2].
4. Practical implications: why definitions matter for life
How love is defined affects real‑world choices and institutions: if love is primarily chemistry, counseling centers on regulation and compatibility; if it is practice, skills and norms for sustaining relationships gain priority; if it is vision, cultivating moral perception or aesthetic appreciation matters [3] [4] [7]. These theoretical commitments carry implicit agendas—medicalizing love favors pharmaceutical or biological interventions, while practice frameworks empower education and social norms—so philosophical accounts map onto policy and personal advice in nonneutral ways [2] [9].
5. Limits of current accounts and continuing mysteries
No single source among philosophers, psychologists, or popular writers fully captures love’s variability: historical, cultural, and linguistic research shows some cultures conceptualize love differently or even lack direct equivalents, undercutting universalist claims [2]. Contemporary philosophy emphasizes pluralism—that love is partly ineffable, partly analyzable—and invites humility about grand reductionist answers while encouraging cross‑disciplinary inquiry [2] [1].
6. Bottom line: what is love?
Love is best understood as a multifaceted cluster of relational phenomena—comprising desires, attachments, practices, and moral commitments—that vary by kind (eros, philia, agape, etc.) and by explanatory lens (biological, perceptual, ethical, or practical); none of these alone suffices to define love but together they explain why love is deep, disruptive, and central to human life [1] [3] [4]. Readers should therefore treat any single definition with suspicion, recognize the agendas behind competing accounts, and allow that part of what people call “love” remains contested and context‑dependent [2] [9].
