Scott Adams frequently reveals persistent and deep-seated ignorance when he strays very far into scientific and philosophical matters on his personal blog. Many times in the past he has, for example, demonstrated no real understanding of science or evolution whenever he writes anything on those topics. More recently he demonstrated an equal absence of understanding about both atheism and agnosticism.
It’s very simple. Agnosticism is a belief in the lack of evidence for God’s existence. Atheism is a symptom of a personality disorder which inordinately affects developmentally challenged young men.
Watch and learn. Science will confirm this in the relatively near future.
