“A scientist can hardly meet with anything more undesirable than to have the foundations give way just as the work is finished. I was put in this position by a letter from Mr. Bertrand Russell when the work was nearly through the press.” WayGivingPositionLettersScientistMathematicsFoundationPressesMathFinishedMathematicalUndesirable Author:Gottlob Frege
