[lit-ideas] Re: Practical Logic [correction]

There's no doubt plenty in what I wrote under this heading earlier
that wants changing but in particular this needs to be clarified.
I wrote


But in modus ponens, no hypothesis or empirical claim is being advanced.
Imagine a meta-if (IF) standing behind the whole schemata. IF says,
'If p, then q, and p, then q.' It doesn't address the truth or falsity of the conditional, the conjoined premise (or the conclusion) but merely says that if the conjoined premises were true, the conclusion would have to be true also. 

Instead: IF says, IF (If p then q, and p) then q.
