I agree that much logic is rationally flawed. It is ironic, I think, that at the TT we have not much else but logic by which to communicate what we each discover of rationality.

That we have to perform a trick to recognize the difference between the rational and the merely logical is mostly, I believe, because we confuse symbols, in this case words, for what our seniors invented the words to re-present (and struggled to have recognized as common experiences).
