Yes you were... You were denying the definition of Bruno (arithmetical realism) by giving yours... then Bruno and Stathis ask for the difference between yours and their definition... Which you respond with a contradiction to say platonism is false... then either you were effectively contradicting yourself or you did not answer Stathis and Bruno question (it's one or the other). > Existence is availability for causal interaction > Numbers are not available for causal interaction > Numbers do not exist That's your definition of existence... this is your claim. Now a definition game will not resolve this problem obviously. > Platonism is the claim that numbers exist > Numbers do not exist > Platonism is false Platonism does not claim number exist by your definition of existence hence your conclusion is ill based.
