Nowhere... is the need more urgent of building a bridge between the... the physical and the moral... - Pierre Teilhard de Chardin

In the end, only the truth will survive.

[W]e realise... the fact and... reason for the diversity of animal behaviour. From the moment we regard evolution as... psychical transformation, we see... a multitude of forms of instincts each corresponding to a... solution of the problem of life. The 'psychical' make-up of an insect is not and cannot be that of a vertebrate ; nor can... [that] of a squirrel be that of a cat or... elephant: this in virtue of the position[s]... on the tree of life. ...[W]e begin to see ...a gradation formed. If instinct is a variable dimension, the instincts will... create, beneath their complexity, a growing system. They will form as a whole a... fan-like structure in which the higher terms on each nervure are recognised... by a greater range of choice and depending on a better defined centre of coordination and consciousness. ...The 'psychical' make-up of a dog... is... superior to that of a mole or a fish. ...[T]he upholders of the spiritual explanation have no need to be disconcerted when they see... in the higher animals (particularly in the great apes) ways and reactions which strangely recall... 'a reasoning soul'. If the story of life is no more than a movement of consciousness veiled by morphology, it is inevitable that... in the proximity of man, the 'psychical' make-ups seem to reach the borders of intelligence.

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.
