As Paul Spudis (who I recently discovered has a blog or two) notes in comments over there, it's a deadly combination of insufferable arrogance and unsurpassed ignorance. Though I think he gives Lou too much credit when he calls it an accomplishment. It comes naturally to him.

'too?' 'to' changes the meaning entirely.

Anyway, I don't particular like the mission statement of the Planetary Society...

Mission statements tend to be too general and arrogant sounding for my taste. I much prefer something a bit more focused. It does seem that mission statements are often an afterthought.
