Enki - you more than lost me with the maths there - but i think your trying to argue that more than one thing can be true - but i dont think Willa was saying only one thing can be true when she said theres only one truth - my impression was she meant concerning the topic at hand there was only one truth.....
i mean obviously theres more than one truth in absolute terms - like im black an im a girl - so thats 2 truths for starters - but..... im either a girl or i aint - so in terms or gender im either one thing or the other there cant be multiple truth to that - thats what i understood her to be meaning - like for example she oviously believes paul existed - you think he didnt - one of you is right - you cant both be right at the same time - to me this just seems kinda simple an logical - if you think im wrong - which no doubt you will can you please try an explain it in words not equations - all that math is startin to make my brain go
