Final answer:
The theme of the Aesop fable 'The Miner' is that true value comes from the use of wealth, rather than its mere possession, and hoarding money without spending is pointless.
Step-by-step explanation:
The theme of the Aesop fable 'The Miner' highlights the folly of valuing wealth over practicality and the potential for money to cause irrational behavior. The miser, who hoards gold without using it, is no better off than if he had a useless stone. The story suggests that the worth of money is not in having it, but in its use.
