Formalism/Substitute/Sign/Symbol/WittgensteinVsFrege: Frege: characters are either mere blackening or signs of something - then what they represent, is their meaning - Wittgenstein: false alternative - E.g. chess pieces: represent nothing - Solution: use like in the game instead of representation of something - ((s) use is more than mere blackening of the paper and less than representation of an object) - Wittgenstein: formalism is not entirely unjustified.
