Our reading
An editorial interpretation.
The speaker singles out Peregrin Took as the most troublesome example of an already inquisitive group. Addressing him by name makes the rebuke pointed. The phrasing suggests exasperation with his curiosity, while the sweeping comparison gives a brief complaint the force of a grand judgment.
