But all of my efforts served only to make me better acquainted with the difficulty, which in itself was something.

Mathematicians are born, not made.
Henri Poincare
Image
Mathematicians do not deal in objects, but in relations between objects thus, they are free to replace some objects by others so long as the relations remain unchanged. Content to them is irrelevant: they are interested in form only.
Henri Poincare
Image
Thought is only a flash between two long nights, but this flash is everything.
Henri Poincare
Image
A scientist worthy of his name, about all a mathematician, experiences in his work the same impression as an artist his pleasure is as great and of the same nature.
Henri Poincare
Image
Geometry is the art of correct reasoning from incorrectly drawn figures.
Henri Poincare
Image
The aim of science is not things themselves, as the dogmatists in their simplicity imagine, but the relation between things.
Henri Poincare
Image
A sane mind should not be guilty of a logical fallacy, yet there are very fine minds incapable of following mathematical demonstrations.
Henri Poincare
Image
Tolstoi explains somewhere in his writings why, in his opinion, “Science for Science's sake” is an absurd conception. We cannot know all the facts, since they are practically infinite in number. We must make a selection. Is it not better to be guided by utility, by our practical, and more especially our moral, necessities?
Henri Poincare
Image
All of mathematics is a tale about groups.
Henri Poincare
Image
Mathematicians do not study objects, but the relations between objects.
Henri Poincare
Image
Every good mathematician should also be a good chess player and vice versa.
Henri Poincare
Image
It is far better to foresee even without certainty than not to foresee at all.
Henri Poincare
Image
We also know how cruel the truth often is, and we wonder whether delusion is not more consoling.
Henri Poincare
Image
One geometry cannot be more true than another it can only be more convenient.
Henri Poincare
Image
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
Henri Poincare
Image
Pure logic could never lead us to anything but tautologies it can create nothing new not from it alone can any science issue.
Henri Poincare
Image
Mathematical discoveries, small or great are never born of spontaneous generation They always presuppose a soil seeded with preliminary knowledge and well prepared by labour, both conscious and subconscious.
Henri Poincare
Image
...the feeling of mathematical beauty, of the harmony of numbers and of forms, of geometric elegance. It is a genuinely aesthetic feeling, which all mathematicians know
Henri Poincare
Image
What is it indeed that gives us the feeling of elegance in a solution, in a demonstration?
Henri Poincare
Image
I entered an omnibus to go to some place or other. At that moment when I put my foot on the step the idea came to me, without anything in my former thoughts seeming to have paved the way for it, that the transformations I had used to define the Fuchsian functions were identical with non-Euclidean geometry.
