I have a friend who claims to be an atheist. He says often that it
requires more faith to be an atheist than to believe in God...
As far as agnosticism, I believe you're right. In my opinion, it is
more of tenable philosophical position. However, I think that it has
more to due with the individual you're talking with than anything
else. In other words, some atheists are very philosphical and present
their case very logically, and some agnosticists really lack logic -
their position is just faith.
Is that what you had on your mind? :)
