Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered.

More quotes by Henri Poincare

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
Experiment is the sole source of truth. It alone can teach us something new it alone can give us certainty.
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
Most striking at first is the appearance of sudden illumination, a manifest sign of long unconscious prior work.
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
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
Guessing before proving! Need I remind you that it is so that all important discoveries have been made?
Henri Poincare
Image
Analyse data just so far as to obtain simplicity and no further.
Henri Poincare
Image
Les faits ne parlent pas. Facts do not speak.
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
Mathematicians do not study objects, but the relations between objects.
Henri Poincare
Image
It is far better to foresee even without certainty than not to foresee at all.
Henri Poincare

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
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
In the old days when people invented a new function they had something useful in mind.
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
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 may happen that small differences in the initial conditions produce very great ones in the final phenomena.
Henri Poincare

Thus, be it understood, to demonstrate a theorem, it is neither necessary nor even advantageous to know what it means.
