„The cowboys have a way of trussing up a steer or a pugnacious bronco which fixes the brute so that it can neither move nor think. This is the hog-tie, and it is what Euclid did to geometry.“

„The right way to ask the question is: How does the concept of a point fit into the logical structure of Euclid's geometry? …It cannot be answered by a definition.“

—  Freeman Dyson, livro Infinite in All Directions
Infinite in All Directions (1988), Context: Euclid... gave his famous definition of a point: "A point is that which has no parts, or which has no magnitude." …A point has no existence by itself. It exists only as a part of the pattern of relationships which constitute the geometry of Euclid. This is what one means when one says that a point is a mathematical abstraction. The question, What is a point? has no satisfactory answer. Euclid's definition certainly does not answer it. The right way to ask the question is: How does the concept of a point fit into the logical structure of Euclid's geometry?... It cannot be answered by a definition. Ch. 2 : Butterflies and Superstrings, p. 17

„You can see for what reason I commend the study of eloquence to you—because we can neither explain what we ourselves want, nor understand the surviving writing written by our ancestors, unless we have thoroughly studied a fixed rule for speaking. For my part, I do not see how there could be others who wish neither to explain what they think, nor to understand what is excellently said.“

„For thousands of years people have been trying to force other people to think their way. Did they succeed? No. Will they succeed? No. Why? Because brute force is not an argument.“

„Geometry can in no way be viewed… as a branch of mathematics; instead, geometry relates to something already given in nature, namely, space. I… realized that there must be a branch of mathematics which yields in a purely abstract way laws similar to geometry.“

„And thus far historians produce the perfection of this science. But Euclid was not much junior to these, who collected elements, and constructed many of those things which were invented by Eudoxus; and perfected many which were discovered by Theætetus. Besides, he reduced to invincible demonstrations, such things as were exhibited by others with a weaker arm. But he lived in the times of the first Ptolemy: for Archimedes mentions Euclid, in his first book, and also in others. Besides, they relate that Euclid was asked by Ptolomy, whether there was any shorter way to the attainment of geometry than by his elementary institution, and that he answered, there was no other royal path which led to geometry. Euclid, therefore, was junior to the familiars of Plato, but more ancient than Eratosthenes and Archimedes (for these lived at one and the same time, according to the tradition of Eratosthenes) but he was of the Platonic sect, and familiar with its philosophy: and from hence he appointed the constitution of those figures which are called Platonic, as the end of his elementary institutions.“

„This intelligence-testing business reminds me of the way they used to weigh hogs in Texas. They would get a long plank, put it over a cross-bar, and somehow tie the hog on one end of the plank. They'd search all around till they found a stone that would balance the weight of the hog and they'd put that on the other end of the plank. Then they'd guess the weight of the stone.“

„Neither lemonade nor anything else can prevent the inroads of old age. At present, I am stoical under its advances, and hope I shall remain so. I have but one prayer at heart; and that is, to have my faculties so far preserved that I can be useful, in some way or other, to the last.“

„Thinking thus he did not move. At last the elephant took him up by his trunk, and dashed him aside.“

Râmakrishna : His Life and Sayings (1898), Context: The Master said: "Everything that exists is God." The pupil understood it literally, but not in the true spirit. While he was passing through a street, he met with an elephant. The driver (mahut) shouted aloud from his high place, "Move away, move away!" The pupil argued in his mind, "Why should I move away? I am God, so is the elephant also God. What fear has God of Himself?" Thinking thus he did not move. At last the elephant took him up by his trunk, and dashed him aside. He was severely hurt, and going back to his Master, he related the whole adventure. The Master said, "All right, you are God. The elephant is God also, but God in the shape of the elephant-driver was warning you also from above. Why did you not pay heed to his warnings?" Saying 15
