La puissance des mouches. Elles gagnent des batailles, empêchent notre âme d’agir, mangent notre corps.
Flies are so mighty that they win battles, paralyse our minds, eat up our bodies.

Consider the hateful brew compounded with gleaming, deadly white lead whose fresh colour is like milk…. Over the victim’s jaws and in the grooves of the gums is plastered an astringent froth, and the furrow of the tongue turns rough on either side, and the depth of the throat grows somewhat dry, and from the pernicious venom follows a dry retching and hawking, for this affliction is severe; meanwhile his spirit sickens and he is worn out with mortal suffering. His body too grows chill, while sometimes his eyes behold strange illusions or else he drowses; nor can he bestir his limbs as heretofore, and he succumbs to the overmastering fatigue.

I came to realize that exaggerated concern about what others are doing can be foolish. It can paralyze effort, and stifle a good idea. One finds that in the history of science almost every problem has been worked out by someone else. This should not discourage anyone from pursuing his own path.

I don’t know if I would call it a miracle. I would call it a spectacular example of what people can do. To me, it’s like putting the first man on the moon or splitting the atom. We’ve shown that if the right treatment is given to people who have a catastrophic injury that they could walk away from it.
Expressing optimism for further recovery for Kevin Everett, a Buffalo Bills football player who suffered a paralyzing spinal injury during a game (9 Sep 2007), but after two days of hospital treatment had begun voluntarily moving his arms and legs. Green credits as significant to the recovery was that within minutes of his injury, the patient was quickly treated with intravenous ice-cold saline solution to induce hypothermia.

I said to myself, if there's a group of these people that are so courageous and so selfless, somebody ought to carry their damn banner and do something about. That's 1965. I was 20 years old. I said I was going to commit my career to curing paralysis.
Referring to the paralyzed veteran volunteers in the spinal cord injury laboratory with whom Green worked while attending medical school.

I’d disband NASA for 10 years and take half its budget to avert natural disasters. We could do it, we’ve got the technology. I'd take the other half to deal with disease and suffering. The time has come to do something bold instead of buying wheelchairs.

The logic of the subject [algebra], which, both educationally and scientifically speaking, is the most important part of it, is wholly neglected. The whole training consists in example grinding. What should have been merely the help to attain the end has become the end itself. The result is that algebra, as we teach it, is neither an art nor a science, but an ill-digested farrago of rules, whose object is the solution of examination problems. … The result, so far as problems worked in examinations go, is, after all, very miserable, as the reiterated complaints of examiners show; the effect on the examinee is a well-known enervation of mind, an almost incurable superficiality, which might be called Problematic Paralysis—a disease which unfits a man to follow an argument extending beyond the length of a printed octavo page.

The surveyor ought to work in solitude. He must no more admit company while mapping than a writer admits visitors to his study while writing. This applies even to geological company, nay, even to the company of a skilled fellow-surveyor... The two authors of this book [Edward Greenly and Howell Williams] once thought that it would be pleasant to have a day's mapping together, and decided to break through their rule. The result was a ludicrous paralysis. The commonest operation seemed a mountain of difficulty. Next day the senior author (whose ground it was) swept an india-rubber over every line and went out again, when, hey presto! And all was clear.

We can’t define anything precisely. If we attempt to, we get into that paralysis of thought that comes to philosophers… one saying to the other: “You don’t know what you are talking about!” The second one says: “What do you mean by know? What do you mean by talking? What do you mean by you?”
