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

...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
A reality completely independent of the spirit that conceives it, sees it, or feels it, is an impossibility. A world so external as that, even if it existed, would be forever inaccessible to us.
Henri Poincare

The mind uses its faculty for creativity only when experience forces it to do so.
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

One would have to have completely forgotten the history of science so as to not remember that the desire to know nature has had the most constant and the happiest influence on the development of mathematics.

Les faits ne parlent pas. Facts do not speak.

Thus, be it understood, to demonstrate a theorem, it is neither necessary nor even advantageous to know what it means.
Henri Poincare
Image
It is the simple hypotheses of which one must be most wary because these are the ones that have the most chances of passing unnoticed.
Henri Poincare

Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.
Henri Poincare
Image
Mathematicians do not study objects, but the relations between objects.
Henri Poincare

Mathematics is the art of giving the same name to different things.
Henri Poincare
Image
When the physicists ask us for the solution of a problem, it is not drudgery that they impose on us, on the contrary, it is us who owe them thanks.
Henri Poincare
Image
Thought is only a flash between two long nights, but this flash is everything.
Henri Poincare
Image
It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.
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
What is a good definition? For the philosopher or the scientist, it is a definition which applies to all the objects to be defined, and applies only to them it is that which satisfies the rules of logic. But in education it is not that it is one that can be understood by the pupils.
Henri Poincare

Intuition is more important to discovery than logic.
Henri Poincare
Image
The subliminal self is in no way inferior to the conscious self. It knows how to choose and to divine.
Henri Poincare
Image
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
