Pure logic could never lead us to anything but tautologies it can create nothing new not from it alone can any science issue.

But for harmony beautiful to contemplate, science would not be worth following.
Henri Poincare
Image
Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.
Henri Poincare
Image
Just as houses are made of stones, so is science made of facts.
Henri Poincare
Image
If we wish to foresee the future of mathematics, our proper course is to study the history and present condition of the science.
Henri Poincare
Image
Why is it that showers and even storms seem to come by chance, so that many people think it quite natural to pray for rain or fine weather, though they would consider it ridiculous to ask for an eclipse by prayer.
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

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
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
Ideas rose in clouds I felt them collide until pairs interlocked, so to speak, making a stable combination.
Henri Poincare
Image
It is through science that we prove, but through intuition that we discover.
Henri Poincare
Image
The mathematical facts worthy of being studied are those which, by their analogy with other facts, are capable of leading us to the knowledge of a physical law. They reveal the kinship between other facts, long known, but wrongly believed to be strangers to one another.
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
Mathematicians are born, not made.
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.
Henri Poincare
Image
Mathematicians do not study objects, but the relations between objects.
Henri Poincare
Image
Zero is the number of objects that satisfy a condition that is never satisfied. But as never means in no case, I do not see that any progress has been made.
Henri Poincare
Image
Doubting everything and believing everything are two equally convenient solutions that guard us from having to think
Henri Poincare
Image
. . . by natural selection our mind has adapted itself to the conditions of the external world. It has adopted the geometry most advantageous to the species or, in other words, the most convenient. Geometry is not true, it is advantageous.
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
The aim of science is not things themselves, as the dogmatists in their simplicity imagine, but the relation between things.
