A Quote by Plato

Let no-one ignorant of geometry enter. Said to have been inscribed above the door of Plato's Academy. — © Plato
Let no-one ignorant of geometry enter. Said to have been inscribed above the door of Plato's Academy.
[Aristotle] was the most eminent of all the pupils of Plato.... He seceded from Plato while he was still alive; so that they tell a story that [Plato] said, " Aristotle has kicked us off, just as chickens do their mother after they have been hatched.
One may enter the literary parlor via just about any door, be it the prison door, the madhouse door, or the brothel door. There is but one door one may not enter it through, which is the child room door. The critics will never forgive you such. The great Rudyard Kipling is one of a number of people to have suffered from this. I keep wondering to myself what this peculiar contempt towards anything related to childhood is all about.
Geometry enlightens the intellect and sets one's mind right. All of its proofs are very clear and orderly. It is hardly possible for errors to enter into geometrical reasoning, because it is well arranged and orderly. Thus, the mind that constantly applies itself to geometry is not likely to fall into error. In this convenient way, the person who knows geometry acquires intelligence.
Diogenes, filthily attired, paced across the splendid carpets in Plato's dwelling. Thus, said he, do I trample on the pride of Plato. Yes, Plato replied, but only with another kind of pride.
You've been busy using your breaking and entering skills," I said. "I just enter. I don't usually break." "You broke down Pitch's door." "Lost my temper." -Ranger and Stephanie
Most governments have been based, practically, on the denial of equal rights of menours began, by affirming those rights. They said, some men are too ignorant, and vicious, to share in government. Possibly so, said we; and, by your system, you would always keep them ignorant, and vicious. We proposed to give all a chance; and we expected the weak to grow stronger, the ignorant wiser; and all better, and happier together.
Said Aristotle unto Plato, 'Have another sweet potato?' Said Plato unto Aristotle, 'Thank you, I prefer the bottle.'
When God gives you a door, if you want access, you go through that door. People didn't like Jesus. Oh, they had all kind of reasons to hate him but Jesus said, "I am the door. Any man who enters must come by me. If you don't come by me," he said, "you're a thief and a robber." Well, if Omarosa Manigault is the door to Donald Trump, well I kind of like that door. That's a pretty door. That's an intelligent door. That's a spiritually rooted door.
Let no one destitute of geometry enter my doors.
Somebody once asked Niels Bohr why he had a horseshoe hanging above the front door of his house. Surely you, a world famous physicist, can't really believe that hanging a horseshoe above your door brings you luck? Of course not, Bohr replied, but I have been reliably informed that it will bring me luck whether I believe in it or not.
The concept of congruence in Euclidean geometry is not exactly the same as that in non-Euclidean geometry. ..."Congruent" means in Euclidean geometry the same as "determining parallelism," a meaning which it does not have in non-Euclidean geometry.
the [coat] rack above his head like a javelin. On the other side of the door was Jace. He blinked. "Is that a coatrack?" Jordan slammed the coatrack down on the ground and sighed. "If you'd been a vampire, this would have been a lot more useful." "Yes," said Jace. "Or, you know, just someone with a lot of coats.
I'm just one of those people that when there's a door that says 'Do Not Enter,' I have to know what's happening on the other side of that door.
Kepler's discovery would not have been possible without the doctrine of conics. Now contemporaries of Kepler-such penetrating minds as Descartes and Pascal-were abandoning the study of geometry ... because they said it was so UTTERLY USELESS. There was the future of the human race almost trembling in the balance; for had not the geometry of conic sections already been worked out in large measure, and had their opinion that only sciences apparently useful ought to be pursued, the nineteenth century would have had none of those characters which distinguish it from the ancien régime.
Analytical geometry has never existed. There are only people who do linear geometry badly, by taking coordinates, and they call this analytical geometry. Out with them!
Metrical geometry is thus a part of descriptive geometry, and descriptive geometry is all geometry.
