To every problem there is already a solution, whether you know it or not. To every sum in there is already a correct answer, whether the mathematician has found it or not.
Grenville KleiserTact, the kind of tact you should cultivate, is not a form of deception or make-believe, but a cultivated taste which gives fine perception in seeing and doing what is best under all circumstances. There is nothing which will so readily bring you into favor, or disarm an opponent, as the right use of tact.
