Men can construct a science with very few instruments, or with very plain instruments; but no one on earth could construct a science with unreliable instruments. A man might work out the whole of mathematics with a handful of pebbles, but not with a handful of clay which was always falling apart into new fragments, and falling together into new combinations. A man might measure heaven and earth with a reed, but not with a growing reed.
Interpretation
Reliable tools and foundation are essential for the pursuit of knowledge and truth.
This quote by Gilbert K. Chesterton emphasizes the importance of having stable and reliable instruments—be they physical tools or conceptual frameworks—in the pursuit of any scientific or mathematical endeavor. While simple tools can yield profound insights, unreliable ones only lead to confusion and errors, highlighting how the integrity of our methods directly influences the quality of our understanding.
In practice
Discussing the importance of good laboratory tools in a science class.
Tradition does not mean a dead town; it does not mean that the living are dead but that the dead are alive. It means that it still matters what Penn did two hundred years ago or what Franklin did a hundred years ago; I never could feel in New York that it mattered what anybody did an hour ago.
I owe my success to having listened respectfully to the very best advice, and then going away and doing the exact opposite.
The good Bishop of Assisi expressed a sort of horror at the hard life which the Little Brothers lived at the Portiuncula, without comforts, without possessions, eating anything they could get and sleeping anyhow on the ground. St. Francis answered him with that curious and almost stunning shrewdness which the unworldly can sometimes wield like a club of stone. He said, 'If we had any possessions, we should need weapons and laws to defend them.
The ordinary scientific man is strictly a sentimentalist. He is a sentimentalist in this essential sense, that he is soaked and swept away by mere associations.
I suppose every one must have reflected how primeval and how poetical are the things that one carries in one's pocket; the pocket-knife, for instance, the type of all human tools, the infant of the sword. Once I planned to write a book of poems entirely about things in my pockets. But I found it would be too long; and the age of the great epics is past.
Madness does not come by breaking out, but by giving in; by settling down in some dirty, little, self-repeating circle of ideas; by being tamed.
Cure yourself of the inclination to bother about how you look to other people. Be concerned only . . . with the idea God has of you.
The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.
I realize today that nothing in the world is more distasteful to a man than to take the path that leads to himself.
People are of two types, they are either your brothers in faith or your equals in humanity.
I believe we shall come to care about people less and less, Helen. The more people one knows, the easier it becomes to replace them. It's one of the curses of London. I quite expect to end my life caring most for a place.
You should not have any special fondness for a particular weapon, or anything else, for that matter. Too much is the same as not enough. Without imitating anyone else, you should have as much weaponry as suits you.
