An agnostic is open to the possiblility of God, just doesn't know...A good discussion can be had with them...not saying you could convince them, but at least they would be fine in a discussion...jmho.
Years ago, when our kids were small, we camped a lot. Up in the mountains, with a clear night, looking up in the heavens one cannot help but believe in a Creator. Its awesome to look at, just as truly looking at a beautiful flower. Misquitos suck...
According to "Webster's Seventh Tattered", agnostic means, "of or relating to the belief that the existence of any ultimate reality ( as God ) is unknown and probably unknowable." This seems to be a much firmer point of view than mere indecision.
Now, in Webster's Eleventh Collegiate, this is repeated, except it adds, with the qualification broadly ( italics in orig,) "one who is not commited to believing in the existence or nonexistence of God or a god". Love that "God or a god" ... sounds like Gog and Magog ! ... well, they are just acceding to the popular usage here, as they have, since the 1960's at least, counted themselves as recorders and not dictators of usage.
“Misquitos suck...”
Literally and figuratively.
If we could communicate with the mosquito, we would find that it contains within itself the flying center of the world. - FN
