This is mathematical induction, not weasel words.<p>1. If X grains is not a heap, X+1 grains is not a heap.
2. 1 grain is not a heap.<p>You might disagree with 1 (or 2, though normally we&#x27;d disagree with one), but &quot;and so on&quot; isn&#x27;t weaseling. It&#x27;s plainly expressing the recursive applicability of 1.
