Resolution of the entropy‐evolution problem was a significant issue for Pierre Teilhard de Chardin throughout his scientific career. Although never truly satisfied with his solution, he proposed that all energy must be psychic and contain two components. Tangential energy is related to physical energy. Radial energy in some way accounts for increasing complexity and consciousness in evolution. Analysis of developments in thermodynamics, statistical mechanics, and information theory show that Gibbs free energy contains both calorimetric and noetic components, thus validating Teilhard's (...) intuition.

Teilhard's texts were published in two complementary publications, the more philosophical‐theological ones in the L'Oeuvres (OV), the scientific ones in the L'Oeuvre Scientifique (OS)1. His letters were published in a nonsystematic way. The publication of the Oeuvres presented thematic compilations. The papers had their own production history, creating different versions. Scientific texts were published by Teilhard in widely dispersed journals and have been collected into L'Oeuvre Scientifique. The scientific status of Teilhard is related to his positions in the scientific world (...) and the continued use of his publications. The influences causing different versions of theological and philosophical papers are analyzed. The present accessibility of the diaries and their importance for a full understanding of Teilhard is elaborated. (shrink)
