It waits somewhere in the dark infinity of time. Perhaps the past. Perhaps the future. Perhaps now. The worst thing.
Whenever something bad happens to me, such as a full quadriceps tendon tear, people always helpfully remark that “it could have been worse.” Some years ago, after that tendon tear, I wrote an essay about this matter which focused on possibility and necessity. That is, whether it could be worse or not. While the tendon tear was perhaps the worst thing to happen to me (as of this writing), I did have some bad things happen this summer and got to hear how things could have been worse. Since it seemed like a fun game, I decided to play along: when lightning took out the pine tree in front of my house I said “why, it could have been worse” and then was hit with inspiration: what would be the worst thing? The thing that which nothing worse can be conceived.
I can say with complete confidence that there must be such a thing. After all, just as there must be a tallest building, there must be the worst thing. But, of course, this would not be much of an essay if I failed to argue for this claim.
Interestingly enough, arguing for the worst thing is rather similar to arguing for the existence of a perfect thing (that is, God). Thomas Aquinas famously made use of his Five Ways to argue for the existence of God and most of these arguments relied on a combination of an infinite regress and a reduction to absurdity. For example, Aquinas argued from the fact that things move to the need for an unmoved mover on the grounds that an infinite regress would arise if everything had to be moved by something else. A regress argument with a reduction to absurdity will serve quite nicely in arguing for the worst thing.
Take any thing. To avoid the usual boring philosophical approach of calling this thing X, I’ll call this thing Troy. If Troy is the worst thing, then the worst thing exists. If Troy is not the worst thing, then there must be another thing that is worse than Troy. That thing, which I will call Sally, is either the worst thing or not. If Sally is the worst thing, then the worst thing exists and is Sally. If it is not Sally, there must be something worse than Sally. This cannot go on to infinity so there must be a thing that is worse than all other things—the worst thing. I’ll call it Dave.
The obvious counter is to throw down the infinity gauntlet: if there is an infinite number of things, there will not be a worst thing. After all, for any thing, there will be an infinite number of other things. As Leibniz claimed, the infinite number cannot be said to be even or odd, therefor in an infinite universe a thing could not be said to be worst.
One might be inclined to reject the infinity gauntlet—after all, even if there is an infinite number of things, each thing would stand in a relation to all other things and there would thus still be a worst thing.
Another obvious counter is to assert that there could be two or more things that are equally bad—that is, identical in their badness. As such, there would not be a worst thing. A counter to this is to follow Leibniz once again and argue that there could not be two identical things—they would need to differ in some way that would make one worse than the other. This could be countered by asserting that the two might be different, yet equally bad. In this case, the response would be to follow the model used in arguing for the best thing (God) and assert that the worst thing would be worst in every possible respect and hence anything equally as bad would be identical and thus there would be one worst thing, not two. I suppose that this would have some consolation value—it would certainly be a scary universe that had multiple worst things.
Of course, this just shows that there is something that is worse than all other things that happen to be—which leaves open the possibility that it is not the worst thing in another sense of the term. So now I will turn to arguing for the truly worst thing.
Another way to argue for the worst thing is to use the model of St. Anselm’s ontological argument. Very crudely put, the ontological argument works like this: God is that which nothing greater can be conceived. If God only existed as an idea in the mind, a greater being can be conceived, namely God existing for real. Thus, God must exist.
In the case of the worst thing, it would be that which nothing worse can be conceived. If it only existed as an idea in the mind, a worse thing can be conceived, namely the worst thing existing for real. Thus, the worst thing must exist.
Another variant on the ontological argument can also be used here. A stock variant is that since God is perfect, He must exist. This is because if He did not exist, He would not be perfect. But He is, so He must. In the case of the worst thing, the worst thing must exist because it is the worst. This is because if it did not exist, it would not be the worst. But it is, so it does. This worst thing would be the truly worst thing (just as God is supposed to be the best thing).
This approach does, of course, inherit the usual difficulties of an ontological argument as pointed out by Gaunilo and Kant (that existence is not a quality). It would certainly be better for the universe and the folks in it for the critics to be right so that there is no worst thing.
