Jen Doll, writing in The Atlantic, on The Complete Calvin and Hobbes:
The spiky-haired, irrepressible boy and his best friend, the tiger named Hobbes, stood for certain truths: That kids were often smarter than adults; that they could and did exist in fully realized imaginative worlds of their own creation; and that those worlds had no limits in terms of possible adventures. Starting from the setup itself—in Calvin's mind, Hobbes is a live tiger; to everyone else in their world, he's just a blank-eyed stuffed animal—there is more than meets the eye. You'd expect no less from a cartoonist who names his 6-year-old main character after 16th-century theologian John Calvin and his stuffed animal friend after 17th-century political philosopher Thomas Hobbes.
I was a latecomer to the strip, actually coming across it in The Days Are Just Packed which, from memory, was a present from someone who very much understood my wild imagination and the ongoing party in my mind. Just perfect really.
