If I gave you one grain of sand—and then another, I think we’d both agree that I haven’t given you a heap.
If I added one more, then still; no heap.
Even if I had given you a small pile of sand, it would be fair to say that just one grain of sand will never be the difference between a small pile and a massive heap.
But at some point—if I kept on adding one grain of sand at a time—we would eventually end up with a heap.
This paradox isn’t new. You may not be surprised when I say that it goes back 2,700 years to Ancient Greece, as so many things do.
