"But all was false and hollow..."

"...On the other side up rose
Belial, in act more graceful and humane;
A fairer person lost not heaven; he seemed
For dignity composed and high exploit:
But all was false and hollow; though his tongue
Dropped manna, and could make the worse appear
The better reason, to perplex and dash
Maturest counsels: for his thoughts were low ..."

John Milton: Paradise Lost, Book 2, 108-115.
