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
Intuition is more important to discovery than logic.
Henri Poincare
Image
Doubting everything and believing everything are two equally convenient solutions that guard us from having to think
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
But all of my efforts served only to make me better acquainted with the difficulty, which in itself was something.
Henri Poincare
Image
It may happen that small differences in the initial conditions produce very great ones in the final phenomena.
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
Geometry is not true, it is advantageous.
Henri Poincare
Image
Just as houses are made of stones, so is science made of facts.
Henri Poincare

Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.
Henri Poincare
Image
If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living
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
Image
What is it indeed that gives us the feeling of elegance in a solution, in a demonstration?
Henri Poincare
Image
All great progress takes place when two sciences come together, and when their resemblance proclaims itself, despite the apparent disparity of their substance.
Henri Poincare
Image
But for harmony beautiful to contemplate, science would not be worth following.
Henri Poincare
Image
In the old days when people invented a new function they had something useful in mind. Now, they invent them deliberately just to invalidate our ancestors' reasoning, and that is all they are ever going to get out of them.
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
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
Mathematicians do not study objects, but relations among objects they are indifferent to the replacement of objects by others as long the relations don't change. Matter is not important, only form interests them.
Henri Poincare
Image
Mathematicians are born, not made.
