I doubt that we're the only presumably--and I use that word advisedly--"intelligent" life form in the universe. I'm not even sure that we're the most intelligent life form on this planet, for that matter...unless our unparalleled ability to find ingenious and highly sophisticated ways to screw things up with our opposable thumbs is what qualifies us for that honor.

We know what we know. We know--and hopefully admit--that there are things we don't know. And we should recognize that there may be--no, make that "are"--things that we don't know we don't know. The humility that that acknowledgment of our limits implies is what I construe as "intelligence".
