he writes in a very eloquent, but very simple style. There is much wry humor he keeps it interesting by varying his blasphemy from mild understatement to over the top.
If you want a shorter read, Why I am Agnostic" is excellent. That one pushed me over the edge from Fundamentalist Christian to Freethinker at age 19 way back in 1984.

"Declaration of the Free"http://www.positiveatheism.org/hist/inglife.htmexcerpt (only 4 paragraphs, see link for complete)
We have no falsehoods to defend
We want the facts;
Our force, our thought, we do not spend
In vain attacks.
And we will never meanly try
To save some fair and pleasing lie.
The simple truth is what we ask,
Not the ideal;
We've set ourselves the noble task
To find the real.
If all there is naught but dross,
We want to know and bear our loss.
We will not willingly be fooled,
By fables nursed;
Our hearts, by earnest thought, are schooled
To bear the worst;
And we can stand erect and dare
All things. all facts that really are.
We have no God to serve or fear,
No hell to shun,
No devil with malicious leer.
When life is done
An endless sleep may close our eyes.
A sleep with neither dreams nor sighs.
