Contemporary debates concerning a universal theory about the praxis of love in human society and culture can benefit greatly from the works of two twentieth‐century thinkers, the French paleontologist and religious writer Pierre Teilhard de Chardin and the Russian‐American sociologist Pitirim A. Sorokin. Although from very different personal and disciplinary backgrounds, they share amazingly similar views on the power of love as transformative energy for transcending the individual self and for creating radically new, collaborative, and cooperative ways of acting that (...) will transform whole societies, indeed the planet. Traditionally, ideas of love have been associated with religion, but these two thinkers advocate systematic scientific research on the production and application of “love‐energy” for the change of culture, social institutions, and human beings. The article is organized in five parts: (1) altruism, science and love: what is love energy? (2) Teilhard's understanding of the phenomenon of love; (3) Sorokin's approach to creative, altruistic love; (4) comparison of Teilhard's and Sorokin's ideas; and (5) performing works of love. As far as I am aware, this is the first article comparing the remarkable parallels as well as distinctive differences between Sorokin's and Teilhard's ideas on love as the highest form of human energy.
