When water is heated to boiling... and one goes on heating it, the first thing that follows—without change of temperature—is a tumultuous expansion of freed and vaporised molecules. Or, taking a series of sections from the base towards the summit of a cone, their area decreases constantly; then suddenly, with another infinitesimal displacement, the surface vanishes leaving us with a point. Thus... we are able to imagine the mechanism involved in the critical threshold of reflection. ...[N]ervous systems followed pari passu the process of increased complication and concentration. Finally, with the primates, an instrument was fashioned so remarkably supple and rich that the step immediately following could not take place without the whole animal psychism being... recast and consolidated on itself. ...When the anthropoid... had been brought 'mentally' to boiling point.... Or... had almost reached the summit of the cone, a final effort took place along the axis. ...What was previously only a centred surface became a centre. By a tiny 'tangential' increase, the 'radial' was turned back on itself and... took an infinite leap forward. Outwardly, almost nothing in the organs had changed. But in depth, a great revolution... consciousness was now leaping and boiling in a space of super-sensory relationships and representations; and simultaneously... was capable of perceiving itself... for the first time.

evolutionary phenomena (of course including the phenomenon known as man) are processus, they can never be evaluated or even adequately described solely or mainly in terms of their origins: they must be defined by their direction,

Are we to foresee man seeking to fullfil himself collectively upon himself, or personally on a greater than himself? Refusal or acceptance of Omega? ... Universal love would only vivify and detach finally a fraction of the noosphere so as to consummate it—the part which decided to "cross the threshold", to get outside itself into the other.
