This book weaves theoretical-empirical threads beyond pragmatic philosophy, quantum cosmology and world affairs. It offers a "quantum-social" approach to inquire solidarity configurations among transnational movements. The first part of the book develops an integrative framework to foreground "quantum-type" features of social fields, virtual movements, and complex encounters. Quantum conceptual keys open new gates for macro-theorizing of "non-locality" and comprehending fields around cognate disciplines like psychology and sociology as well as international studies. Accordingly, emotional "indeterminacy" is found fundamental for understanding mesoscopic dynamics of virtual mobilizations. All along micro-layers, phenomena of "entanglement" mold multiple pathways for transversal solidarities. The empirical second part looks at how transnational solidarity springs emerge under "quantum-like" contexts of liberation/revolution-redemption/resistance movements. Emotional memories and affective imageries dynamically co-mingle across flowing fields and moving habitats of "1968-71" and "2008-11." Affective waves and sentimental circulations shape sanctified-secularized constellations of altruisms and sacrifices through which solidarities spin.
