It’s about freeing our imagination to leap from one idea to the next to the next, even when those leaps seem illogical or impossible. And it is precisely that capacity to link wildly disparate ideas that enabled people, through thousands of generations of trial and error, to move from cave to skyscraper to space station, and from drum to telegraph to iPhone.
In a way, the pun was humanity’s first hyperlink, a way to identify and articulate potential connections that aren’t necessarily or immediately apparent. Punning was and remains a way to sling a verbal rope, in an instant, across vast conceptual canyons. It is this same urge to imagine, explore and establish new connections that fuels creativity generally, and science specifically. Not that puns are a substitute for reason, but neither is reason a substitute for imagination. If imagination didn’t exist, what cause would reason have to set out on a given journey, to prove or disprove a given proposition? Puns reveal a mind free to roam frontiers of possibility, without shame or fear of being wrong.
