This chapter outlines the second of the three meta-categories that together constitute the theory of wellbeing presented in the book. Its focus is relationships, which constitute the main way in which wellbeing is influenced. This meta-category comprises two subsidiary categories, love (i.e., close bonds with select others), and prosociality (connections with people ‘in general’). These in turn are woven together from multiple themes, identified through the analysis of untranslatable words. With love, 14 different types were identified, which were grouped into four main themes: non-personal (e.g., for objects); caring (e.g., for family members); romantic (e.g., for one’s ‘partner’); and transcendent (e.g., for a spiritual figure). With prosociality, five main themes were found: socialising and congregating; morals and ethics; compassion and kindness; interaction and communication; and communality. Together, these categories and themes cover the diverse ways in which relationships can contribute to wellbeing.
