Best Album Cover Ever

Found this on Wikipedia today when I got curious as to the origins of
the phrase "Ghost in the Machine."

One of the book's central concepts is that as the human brain has grown, it has built upon earlier more primitive brain structures, and that these are the "ghost in the machine" of the title. Koestler's theory is that at times these structures can overpower higher logical functions, and are responsible for hate, anger and other such destructive impulses.

Interesting, no?
