"You say that, in the present state of science, it is wiser to have no opinion: well, I have an opinion, not a sentimental one, but a rational one, having acquired a right to it by twenty years of assiduous labour, and it would be wise in every impartial mind to share it. My opinion — nay more, my conviction — is that, in the present state of science, as you rightly say, spontaneous generation is a chimera ; and it would be impossible for you to contradict me, for my experiments all stand forth to prove that spontaneous generation is a chimera. What is then your judgment on my experiments? Have I not a hundred times placed organic matter in contact with pure air in the best conditions for it to produce life spontaneously? Have I not practised on these organic materia which are most favourable, according to all accounts, to the genesis of spontaneity, such as blood, urine, and grape juice? How is it that you do not see the essential difference between my opponents and myself? Not only have I contradicted, proof in hand, every one of their assertions, while they have never dared to seriously contradict one of mine, but, for them, every cause of error benefits their opinion. For me, affirming as I do that there are no spontaneous fermentations, I am bound to eliminate every cause of error, every perturbing influence, I can maintain my results only by means of most irreproachable experiments; their opinions, on the contrary, profit by every insufficient experiment and that is where they find their support."

"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."

- Pierre Teilhard de Chardin
