"Positive reinforcement for continuing to be wrong instead of quiet!  Now, really I only told you half of a proverb, just then.  The real proverb says that to ask what a proposition means, we ask what you should see that's different, depending on whether the proposition is true or false.  Yesterday, water was liquid; tomorrow, water won't be liquid.  How are yesterday and tomorrow different?  Well, yesterday, when I poured water from the cup, it spread out over the floor, in puddles where it clung to itself.  So if tomorrow, I pour out water, and it stays in the same shape as when it left the cup, then tomorrow, 'water is liquid' is false.  Yesterday, you used a spell to duplicate something - let's say a small flower, a dandelion - and the duplicate dandelion seemed just the same as the original.  Tomorrow, you use a spell to duplicate a dandelion, and the resulting flower is blue instead of yellow.  Is one no longer equal to one, tomorrow?  Yesterday, one equaled one; tomorrow, it won't.  What will you see tomorrow that's different from today?"
