Les mathématiques selon B. Russell et E. Borel / Mathematics according to B. Russell and E. Borel
" Mathematics may be defined as the the subject in which we never know
what we are talking about, not whether what we are saying is true "
Bertrand Russel In 'Recent Work on the Principles of Mathematics', International Monthly (1901)
« [...] les mathématiques sont la seule science où l'on sait
toujours de quoi l'on parle et où l'on est certain que ce que l'on
dit est vrai » *
Emile Borel, après avoir cité B. Russell in Les grands courants
de la pensée mathématique, dir. par Le Lionnais F.
