As Rodney Stark writes in his new book, For the Glory of God, “every educated person” of Columbus’s time, especially Christian clergy, “knew the earth was round.”

What a ridiculous, unproveable statement.

More than 800 years before Columbus’s voyage, Bede, the church historian, taught this, as did Hildegard of Bingen and Thomas Aquinas.

Can someone please point out exactly where Hildegard von Bingen taught this? I've read her extensively, and don't recall anything even remotely relating to this.

What a ridiculous, unproveable statement.

No more "unproveable" than the statement: American High School graduates know what the First Amendment is." What's your point?
