This handbook presents an international state-of-the-art book on love in research and practice. It is anchored in classical, contemporary and postmodern perspectives and various disciplines. The book expands previous theoretical, empirical and applied research by presenting new transcultural and transdisciplinary approaches. The authors describe concepts and theories of love from cultural viewpoints with regard to manifestations of love in digital, social, cultural and political contexts. They also focus on love in the context of religion, belief systems, family and intergenerational relations, in the context of counselling, therapy and psychiatry. Additionally, authors explore love in the context of globalisation, in the literature, in workplace and business contexts and with regard to its dark side.
