Le théorème de Birkhoff affirme l'existence de points fixes pour un difféomorphisme de l'anneau S^1\times [-1,1], qui préserve la mesure de Lebesgue, et qui induit un difféomorphisme croissant sur S^1\times {1} et un difféomorphisme décroissant sur S^1\times {-1}.

L'important, ce n'est pas ce qu'on fait de nous, mais ce que nous faisons nous-même de ce qu'on a fait de nous
Nous ne tenons à nos droits individuels que dans le cadre d'un vaste projet qui tendrait à nous conférer l'existence qu'à partir de la fonction que nous remplissons

la vie n'est pas trop courte, c'est nous qui la perdons.

Happiness isn't something you experience; it's something you remember.

People say that what we are seeking is a meaning for life. I don't think this is what we're really seking. I think what we're seeking is an experience of being alive.
  — Joseph Campbell (The power of myth)

In the process of searching for a new focus, it is almost inevitable that the "big" questions will creep in. There is pressure from pseudo-philosophers everywhere to cast aside the impertinent and answer the eternal. Two popular examples are "What is the meaning of life?" and "what is the point of it all?". [...] I am 100% convinced that most big questions we feel compelled to face -handed down through centuries of overthinking and mistranslation- use terms so undefined as to make attempting to answer them a complete waste of time. Consider the question of questions : What is the meaning of life? If pressed, I have but one response : it is the characteristic state or or condition of a living organism. "But that's just a definition", the questionner will retort, "that's not what I mean at all". What do you mean then? Until the question is clear -each term in it defined- there is no point in answering it. The "meaning" of "life" question is unanswerable without further elaboration.

Parmi les gens inaptes à la philosophie, et au nombre desquels il faut compter tous ceux qui n'ont pas étudié la doctrine quantienne - par conséquent, la plupart des étrangers, et, en allemagne, un grand nombre de médecins et d'hommes du même accabit qui philosophes de confiance sur la base de leur catéchisme -, on retrouve encore la vielle opposition radicalement fausse entre l'esprit et la matière. [...] En vérité, il n'y a ni esprit ni matière, mais beaucoup de sottise et d'extravagance dans le monde. L'effort de la pesanteur dans la pierre est tout aussi inexplicable que la pensée dans le cerveau humain, et permettrait donc de conclure à un esprit de la pierre. (p35, ed. Livre de Poche)

Ce que tu as hérité de tes pères, Acquiers-le, pour mieux le posséder

[...] et quoique l'argent en lui-même puisse ne pas suffir à rendre les gens importants, il est difficile d'être important sans argent. D'ailleurs, on mesure l'intelligence à l'argnt gagné. Un hommequi gagne baucoup d'argent est un homme intelligent, un homme qui ne le fait pas, ne l'est pas. Personne n'aime à être pris pour un imbécile. C'est pourquoi, lorsque le marché subit des fluctuations, les gens éprouvent ce que les étudiants doivent ressentir à leurs examens. (p.46) La plupart du temps, le travail que beaucoup de gens ont à faire n'est pas intéressant en soi, mais même ce travail offre de grands avantages. Tout d'abord, il occupe une grande partie de la journée sans que l'on ait bsoin de décider ce que l'on va faire. La plupart des gens, si on les laisse choisir librement l'emploi de leur temps, sont en peine de trouver quoi que ce soit d'assez agréable pour les occuper. Et tout ce qu'ils décident ne les empêchent pas d'être tourmentés par l'idée qu'ils auraient pu fair quelque chose de plus agréable. Le dernier degré de civilisation consiste à pouvoir utiliser intelligemment ses moments de loisir et, à l'heure actuelle, très peu de gens ont atteint ce niveau. (p.191) [sur l'éducation des jeunes] et en même temps que les fait qui tendent à mettre l'accent sur le rôle insignifiant de l'individu, je leur présenterai un tout autre groupe de faits déstinés à bien leur faire comprendre la grandeur dont l'individu est capable, et je leur montrerais que dans tous les abîmes de l'espace stellaire rien ne nous est connu qui ait autant de valeur. (p.207, ed. Payot)

L'humour a été pour moi, tout le long du chemin, un fraternel compagnonnage; je lui dois mes seuls instants veritables de triomphes sur l'adversité. Personne n'est jamais n'est jamais parvenu à m'arracher cette arme, et je la retourne d'autant plus volontier contre moi-même, qu'à travers le "je" et le "moi", c'est à notre condition profonde que j'en ai. L'humour est une déclaration de dignité, une affirmation de la supériorité de l'homme sur ce qui lui arrive (p.160, ed. Folio) Je brûlais un feu rouge et un flic m'arrêta d'un coup de sifflet indigné. -Alors, quoi? gueula-t-il -Rien, lui dis-je en rigolant. La vie est belle ! -Allez, roule, cédant à ce mot de passe, en vrai Français. J'étais jeune, plus jeune que je ne le croyais. Ma naïveté cependant était vieille et désabusée. Eternelle en vérité : je la retrouve dans chaque génération nouvelle, depuis celle des "rats" de Saint-Germain-des-Prés, de 1947, jusqu'à la beat generation californienne qu'il m'arrive de fréquenter parfois, pour m'amuser à reconnaître, en d'autres lieux et sur d'autres visages, les grimaces de mes vingt ans.

The kindly search for growth, the gracious desire to exist of flowers, my near ecstasy among them The privilege to witness my existence - you too must seek the sun...

You have the possibility to give light a dimension in time. —Jonas Mekas, 1978

Eccentricity is not, as dull people would have us believe, a form of madness. It is often a kind of innocent pride, and the man of genius and the aristocrat are frequently regarded as eccentrics because genius and aristocrat are entirely unafraid of and uninfluenced by the opinions and vagaries of the crowd.
  — Edith Sitwell

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

It is a far, far better thing to have a firm anchor in nonsense than to put out on the troubled sea of thought.
