Intuition is more important to discovery than logic.
Henri Poincare
Image
Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.
Henri Poincare
Image
All of mathematics is a tale about groups.
Henri Poincare
Image
For a long time the objects that mathematicians dealt with were mostly ill-defined one believed one knew them, but one represented them with the senses and imagination but one had but a rough picture and not a precise idea on which reasoning could take hold.
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
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

Geometry is not true, it is advantageous.
Henri Poincare
Image
But for harmony beautiful to contemplate, science would not be worth following.
Henri Poincare
Image
We also know how cruel the truth often is, and we wonder whether delusion is not more consoling.
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
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

How is error possible in mathematics?
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
Image
Every good mathematician should also be a good chess player and vice versa.
Henri Poincare
Image
The mind uses its faculty for creativity only when experience forces it to do so.
Henri Poincare
Image
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.
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
How is it that there are so many minds that are incapable of understanding mathematics? ... the skeleton of our understanding, ... and actually they are the majority. ... We have here a problem that is not easy of solution, but yet must engage the attention of all who wish to devote themselves to education.
Henri Poincare

In the old days when people invented a new function they had something useful in mind.

Geometry is the art of correct reasoning from incorrectly drawn figures.
