French Jesuit paleontologist (Sarcenat, Puy-de-Dôme, 1881 - New York 1955). The scientific work of Teilhard de Chardin is situated primarily in Asia: discovery of the Peking Man (1929), explorations in India, in Java, participation in the Yellow Crossing (1931, etc.). His theological and philosophical writings, banned from publication during his lifetime, have been disseminated since his death. Enlightened by a synthesizing vision of the universal unfolding of evolution, they give validity to the phenomenon of the cerebral complexification of the human phylum, ending in the abrupt appearance of the consciousness of self (the "threshold" of reflection), then in a worldwide communication network of human thought, the noosphere, at the heart of which is acting "Christ, the capstone of evolucetion", who is conducting humanity, in a simultaneously immanent and transcendent fashion, towards the "Omega point" (the Kingdom of God). His principal work, the Phenomenon of Man,appeared after his death."

Su principal aporte: La noogenesis y la noosfera

Noogenesis, from the Greek noos = psyche (soul, spirit, thought, mind, consciousness) and genesis = origin (formation, creation, such as "the creation of the world"), is a word which indicates the act of the creation of something psychic.

Noosphere, also from the Greek noos = psyche (soul, spirit, thought, mind, consciousness) and sphere (a body limited by a round surface) , is a word which represents the psychic layer born of Noogenesis which is growing and enveloping our planet above the Biosphere (the mass of living beings which covers the globe).

According to Teillhard, there exists, beyond the laws of physics, another fundamental principle of organization of the universe, another dimension: the infinitely complex. Starting from the simplest to the most complex, all matter can be put in allignement along an axis, from the most elementary particle to the most complex organism.

In this progression towards an ever increasing complexity, of which the human being is the highest grade, evolution is not linear but proceeds by a series of quantitative then qualitative leaps. When a level of complexity reaches its point of maximum complexity, it jumps to a new different level and organization of its wholeness. The more matter becomes complex, the more it approaches to awareness. With the human being, Love begins to actualize in tangible form its potential. Yet the human being is only one of the stages: the unification of humanity on a world scale coincides with the emergence of noosphere, the world of thought, the global consciousness.
