I'm only familiar with Roger Ebert from his days with the late Gene Siskel. I've never given him much thought because I've only heard him talk about movies and not anything--dare I say?--really meaningful. Today I came across a blog entry of his where he contemplates something really meaningful.
In the entry he mentions an entry he made last December 3. It's actually a spot-on rip into Ben Stein and his movie Expelled: No Intelligence Allowed.
And for an interesting experience, try the religion/belief test he mentions.
