THE SORITES PARADOX (OR HOW TO ACHIEVE A STONEHEAP)
In the sixth century BC Eubulides of Miletus described the following puzzle, centring around the vague word ‘stoneheap’ (Greek: soros). One stone does not make a stoneheap, Eubulides observed. But if something is too small to be a stoneheap, you cannot turn it into a stoneheap by adding just one stone. Clearly then, two stones do not make a stoneheap either. But by the same reasoning, nor do three stones, and so on. Consequently, no finite number of stones can ever make a stoneheap.
