Do you need some semantic machinery to model modal talk? For just $1.50 each, we have possible worlds for sale.
You can buy the whole set of worlds for just $500 million: a massive bargain, since the set contains uncountably many worlds. However, please see postage and handling information for information about the receipt of your worlds.
Please note. If you buy the whole set of possible worlds, we cannot post these together. Instead, we will post our the worlds, one world at a time. PLEASE do not contact us to tell us that although you have received uncountably many worlds, there are still worlds missing. We are doing our best.
ALSO NOTE: postage and handling is $20.00 per world.
