If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living

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
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
Mathematicians are born, not made.
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.
Henri Poincare

It is far better to foresee even without certainty than not to foresee at all.
Henri Poincare
Image
Analyse data just so far as to obtain simplicity and no further.
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
Just as houses are made of stones, so is science made of facts.
Henri Poincare
Image
Mathematics has a threefold purpose. It must provide an instrument for the study of nature. But this is not all: it has a philosophical purpose, and, I daresay, an aesthetic purpose.
Henri Poincare
Image
Intuition is more important to discovery than logic.
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
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
Mathematics is the art of giving the same name to different things.
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
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
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
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
Image
Geometry is not true, it is advantageous.
Henri Poincare
Image
Ideas rose in clouds I felt them collide until pairs interlocked, so to speak, making a stable combination.
Henri Poincare
Image
Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.
