We all live in the real world, but at some point in time, we venture into possible worlds. Maybe you're a lover whose excursion into the alternate universe takes you to a place where you ended up getting married to your high school sweetheart instead of breaking up. Or maybe you're an adventurer who ponders the possible future where you journey to a faraway, remote, undiscovered planet. Or maybe you like to throw off all semblance of realism and you place yourself in a world where dragons or wizards exist. I don't know which world you love to enter, as there are an infinite amount to choose from. But I know I can tell you a world in which you will never, nor can ever enter, even in your imagination - the impossible world.
I can guarantee you that you have never - even in your imagination - visited a world where there are square circles or married bachelors. While one could conceive of a world in which dragons existed, since there is nothing in our world indicating that these creatures are logically impossible, we cannot imagine a world where square circles exist. Each, by definition, excludes the other. Philosophers love thinking about impossible worlds, though they can never enter them. This is because impossible worlds are an extremely useful tool we can use to test out the viability of an idea. Running an idea through this test doesn't prove the idea is true, only that it could be true. However, if an idea fails this test, we can remove it from the realm of possibilities and learn important information from it. So let's explore some worlds together by addressing a question I had recently: Is there a possible world where fallen humanity exists, but Jesus does not die for them?
