All quotes from Pierre Teilhard de Chardin’s

A sense of collectivity, arising in our minds out of the evolutionary sense, has imposed a framework of entirely new dimensions upon all our thinking; so that mankind has come to present itself to our gaze less and less as a haphazard and extrinsic association of individuals, and increasingly as a biological entity wherein, in some sort, the proceedings and the necessities of the universe in movement are furthered and achieve their culmination. We feel that the relation between Society and Social Organism is no longer a matter of symbolism but must be treated in realistic terms.

We must enlarge our approach to encompass the formation, taking place before our eyes and arising out of this factor of hominization, of a particular biological entity such as has never before existed on earth—the growth, outside and above the biosphere, of an added planetary layer, an envelope of thinking substance, to which, for the sake of convenience and symmetry, I have given the name of the Noösphere.

That we must proceed slowly and critically in this attempt to construct an “anatomy” of society is evident.

What has not yet been sufficiently taken into account, although it explains everything, is the extent to which this process of mechanization is a collective affair, and the way in which it finally creates, on the periphery of the human race, an organism that is collective in its nature and amplitude.

To an increasing extent every machine comes into being as a function of every other machine; and, again to an increasing extent, all the machines on earth, taken together, tend to form a single, vast, organized mechanism.

On the one hand we have a single brain, formed of nervous nuclei, and on the other a Brain of brains. It is true that between these two organic complexes a major difference exists. Whereas in the case of the individual brain thought emerges from a system of nonthinking nervous fibers, in the case of the collective brain each separate unit is in itself an autonomous center of reflection.

I am thinking, of course, in the first place of the extraordinary network of radio and television communications which, perhaps anticipating the direct syntonization of brains through the mysterious power of telepathy, already link us all in a sort of “etherized” universal consciousness.

The population on the limited surface of this planet which bears us is increasing in almost geometrical progression; while at the same time the scope of each human molecule, in terms of movement, information, and influence, is becoming rapidly coextensive with the whole surface of the globe. A state of tightening compression, in short; but even more, thanks to the biological intermingling developed to its uttermost extent by the appearance of reflection, a state of organized compenetration, in which each element is linked with every other.

No one can deny that a network (a world network) of economic and psychic affiliations is being woven at ever-increasing speed which envelops and constantly penetrates more deeply within each of us. With every day that passes it becomes a little more impossible for us to act or think otherwise than collectively.

We begin to catch sight of it in the study of an all too familiar phenomenon, disquieting in appearance, but in fact highly revealing and reassuring—the phenomenon of unemployment. Owing to the extraordinarily rapid development of the machine a rapidly increasing number of workers, running into tens of millions, are out of work. The experts gaze in dismay at this economic apparatus, their own creation, which instead of absorbing all the units of human energy with which they furnish it rejects an increasing number, as though the machine they devised were working to defeat their purpose. Economists are horrified by the growing number of idle hands. Why do they not look a little more to biology for guidance and enlightenment?

Let the theorists consider themselves. How are they capable of reasoning at all if not because within them their visceral system has been taught to function automatically, while around them society is so well organized that they have both the strength and the leisure to calculate and reflect? What is true for each individual man is precisely what is happening at this moment on the higher level of mankind. Like a heavenly body that heats as it contracts, such, and in a twofold respect, is the Noösphere: first in intensity, the degree in which its tension and psychic temperature are heightened by the coming together and mutual stimulation of thinking centers throughout its extent; and also quantitatively through the growing number of people able to use their brains because they are freed from the need to labor with their hands.

Understanding, discovery, invention… From the first awakening of its reflective consciousness, humanity has been possessed by the demon of discovery; but until a very recent epoch this profound need remained latent, diffused and unorganized in the human mass. In every past generation true seekers, those by vocation or profession, are to be found; but in the past they were no more than a handful of individuals, generally isolated, and of a type that was virtually abnormal—the “inquisitive.” Today, without our having noticed it, the situation is entirely changed. In fields embracing every aspect of physical matter, life, and thought, the research-workers are to be numbered in hundreds of thousands, and they no longer work in isolation but in teams endowed with penetrative powers that it seems nothing can withstand.

The enormous surplus of free energy released by the in-folding of the Noösphere is destined by a natural evolutionary process to flow into the construction and functioning of what I have called its “Brain.” As in the case of all the organisms preceding it, but on an immense scale, humanity is in process of “cerebralizing” itself. And our proper biological course, in making use of what we call our leisure, is to devote it to a new kind of work on a higher plane: that is to say, to a general and concerted effort of vision. The Noösphere, in short, is a stupendous thinking machine.

Until now we have never seen mind manifest itself on this planet except in separated groups and in the static state. What sort of current will be generated, what unknown territory will be opened up, when the circuit is suddenly completed?

If the power of attraction between simple atoms is so great, what may we not expect if similar bonds are contracted between human molecules? Humanity, as I have said, is building its composite brain beneath our eyes.

Life and consciousness are no longer chance anomalies in nature; rather, we find in biology a complement to the physics of matter.
