Goliath
Goliath is described in the biblical Book of Samuel as a Philistine giant defeated by the young David in single combat. The story signified Saul's unfitness to rule, as Saul himself should have fought for the Kingdom of Israel.
David and Goliath (book)
"To read "David and Goliath" is to suffer the discomfort of watching a formidably intelligent author flailing—by citing all manner of social-scientific studies and battering us with charts and tables and graphs—to prove something that no one would disagree with in the first place", wrote Craig Seligman for Bloomberg News. "The further I read into "David and Goliath," the more irritated I got. I wasn’t persuaded there was much of a subject there, but what really bugged me was the tone." Seligman concluded, "[I]n the past I’ve always felt flattered by Gladwell’s writing. I like having things explained to me. But I don’t like being talked down to by someone who’s telling me things I already know."
