>Human beings are both intelligent and self-conscious but, if it may be
>easier to give a theoretical definition of consciousness than of
>intelligence, it is much more difficult to tell whether a being is
>self-conscious or not. Besides, it is not even clear whether consciousness
>is a discrete characteristic (i.e., a characteristic that either is present
>or is not), or a continuous one (i.e., one that may exist in different
>degrees).

>And later:

>On Earth, consciousness and intelligence appear to be strictly related to
>each other. Will it be so when (and if) we discover other intelligent
>beings?

>When we say we are looking for extraterrestrial intelligence, are we
>looking for only intelligent beings, or conscious beings, or beings like
>ourselves who are both? When we search for extraterrestrial intelligence,
>are we actually searching for extraterrestrial minds?
>
>So many questions, and looming above them all that big Fermi question
>where are they? I suspect SETI will be a long, hard search. And if it ever
>does snag an undisputed signal from an extraterrestrial civilization, I
>would wager that it wont be a directed beacon but an extraneous
