the logical form is if then then if (if 'then' then 'if')
like, if there's an effect then there's a cause because there's a then there's a because proposition a: b -> a truth table for proposition a: b - > a 0 1 0 : if not a, then a* 0 1 1 : if a, then a 1 0 0 : if not a, then not a 1 1 1 : if a, then a *a contradiction occurs only when a and b are false, then the proposition is true, which is false. proposition cause: if effect then cause. it's true while it's false. proposition proposition: if then then if. true while false. that's my brother, not born, not dead. he's unthinkable. and my mother, she'll be alone in the cause. but i'll think of her. __ isbn 82-92428-08-9
