1 - I suspect depending on time zone Camotero is going to have a good reply!
2- it's not so much that the words themselves are the issue as much as the way that they are employed. Words too are just tools, just like the virtues! :-). Even "greatest good" can be wielded helpfully - we agree on that - but the issue of "how" I think is deeper than it appears.
If wielded in a way that implies that there is but one conceptual path to follow, as if there is magic in numbers or words as Plato would imply, then that is very damaging.
If wielded using "true philosophy" however then it's the most helpful way of explaining life. Using words to explain that words cannot suffice to show us the way is tricky business!
