Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.
Modern masters of science are much impressed with the need of beginning all inquiry with a fact. The ancient masters of religion were quite equally impressed with that necessity. They began with the fact of sin-a fact as practical as potatoes. Whether or not man could be washed in miraculous waters, there was no doubt at any rate that he wanted washing.
Index-learning turns no student pale,
Yet holds the eel of Science by the tail.
Index-learning is a term used to mock pretenders who acquire superficial knowledge merely by consulting indexes.
Ere land and sea and the all-covering sky Were made, in the whole world the countenance Of nature was the same, all one, well named Chaos, a raw and undivided mass, Naught but a lifeless bulk, with warring seeds Of ill-joined elements compressed together.
"She can't do Subtraction." said the White Queen. "Can you do Division? Divide a loaf by a knife-what's the answer to that?" "I suppose-" Alice was beginning, but the Red Queen answered for her. "Bread-and-butter, of course."
Science is continually correcting what it has said. Fertile corrections... science is a ladder... poetry is a winged flight... An artistic masterpiece exists for all time... Dante does not efface Homer.
We are not clear as to the role in life of these chemicals; nor are we clear as to the role of the physician. You know, of course, that in ancient times there was no clear distinction between priest and physician.
We must not overlook the role that extremists play. They are the gadflies that keep society from being too complacent or self-satisfied; they are, if sound, the spearhead of progress. If they are fundamentally wrong, free discussion will in time put an end to them.
Widespread intellectual and moral docility may be convenient for leaders in the short term, but it is suicidal for nations in the long term. One of the criteria for national leadership should therefore be a talent for understanding, encouraging, and making constructive use of vigorous criticism.
Not from the stars do I my judgement pluck, And yet methinks I have astronomy. But not to tell of good or evil luck, Of plagues, of dearths, or season's quality; Nor can I fortune to brief minutes tell ... Or say with princes if it shall go well.
But in physics I soon learned to scent out the paths that led to the depths, and to disregard everything else, all the many things that clutter up the mind, and divert it from the essential. The hitch in this was, of course, the fact that one had to cram all this stuff into one's mind for the examination, whether one liked it or not.
That is another of your odd notions," said the Prefect, who had a fashion of calling every thing "odd" that was beyond his comprehension, and thus lived amid an absolute legion of "oddities.
For nature by the same cause, provided it remain in the same condition, always produces the same effect, so that either coming-to-be or passing-away will always result.
A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable.
This is the patent-age of new inventions For killing bodies, and for saving souls, All propagated with the best intentions; Sir Humphrey Davy's lantern, by which coals Are safely mined for in the mode he mentions, Tombuctoo travels, voyages to the Poles, Are ways to benefit mankind, as true, Perhaps, as shooting them at Waterloo.
