Calvin and Hobbes by Bill Watterson for August 12, 2015
Calvin: "We rely on sight to confirm the existence of things. We don't believe in things we can't see" Calvin: "So how do we know that no-see-ums exist? Verification is rules out by definition!" Calvin: "It's an ontological quandary" Hobbes: "Hold still a moment" Calvin: "Ooh. I itch!" Hobbes: "Glad I could help"
