Hominisation
For Teilhard de Chardin, *hominization* marks the crossing of the "threshold" of reflection: the moment when life, in man, turns back upon itself and becomes capable of knowing itself. This is not one more stage in animal evolution, but a change of state—the passage from instinct to thought. The term encompasses two scales: the individual threshold, where a being attains reflective consciousness, and the collective threshold, where the entire species becomes humanized and spiritualized through the course of civilization.
C’est à ce grand processus de sublimation qu’il convient d’appliquer, avec toute sa force, le terme d’Hominisation. L’Hominisation, qui est d’abord, si l’on veut, la saute individuelle, instantanée, de l’instinct à la pensée. Mais l’Hominisation qui est aussi, en un sens plus large, la spiritualisation phylétique, progressive, en la Civilisation humaine, de toutes les forces contenues dans l’Animalité.
Teilhard coins hominisation to name what no biological term could grasp: not the emergence of a new animal, but the sudden appearance of reflective thought. Life, he says, does not merely evolve; at a certain threshold, it “turns back on itself,” and a being begins to know itself. This is the “individual, instantaneous leap from instinct to thought”—a leap of kind, not degree. The eye that saw the world becomes an eye that knows it sees.
The word operates on two scales. There is the elemental step—the hominisation of the individual, the moment a consciousness gains self-awareness—and the phylogenetic step, the hominisation of the species, that “progressive spiritualization” by which humanity as a whole takes shape through civilization. The same arc then extends into collective thought, the reflective layer enveloping the planet: what Teilhard calls the noosphere, born of a noogenesis that propels the whole toward the Omega Point. Hominisation is the hinge of this movement toward ever-greater complexity-consciousness.
Hominisation ≠ biological evolution. Evolution arranges degrees—a finer organ, a larger brain—within the continuity of a single fabric of life. Hominisation marks a discontinuity: a change of state, the shift from being closed upon the world to being turned inward. The anatomical difference between humans and animals may remain slight; the difference between a being that thinks and one that does not, Teilhard argues, is absolute.
