ACTUALLY, there are glues that remain usable. Pressure sensitive adhesive is one. Also, consider the longevity of tree sap/gums.
No, it’s not a perfect analogy. No one has found a perfect analogy. There’s analogues with hydraulics and such (water in pipes is one).
But I’ve yet to find an analogy that captures binding until now.
Of course, like all metaphors, it “holds up” only to a point and from that point it ceases to function as a visualization tool.
BUT, you can go far with glue.
Plus, it’s not difficult to imagine glue that stays always pliable and can be reused.
Ultimately, that’s all I want to do in this: Try to think of plausible notions that are unexpected but shine light on things in a novel way to expose hidden connections.
Look how far “particle wave” has gotten us? So, why not “glue but it doesn’t dry”
