(Roughly) Daily“Counterfactual reasoning, which deals with what-ifs, might strike some readers as unscientific. Indeed, empirical observation can never confirm or refute the answers to such questions.”*..
… still, we ask of our history, our reality “what if?”… The estimable Colin McGinn ponders why…
In a world with less gravity, the birds would be huge. In a world with more gravity, only insects would fly. In a world with more light and plant predators, plants would have consciousness and advanced intelligence. In a world with greater water resistance, whales would be small. In a colder world, there would be no cold-blooded animals. In a hotter world, all animals would be cold-blooded. In a wetter world, we would have gills. In a drier world, life would begin on the land, if it begins at all. In a world without tool-forming materials, we would still be walking on four legs. In a world with only predators, there would be no life. In a world without predators, life would be simple and boring. In a world without a sun, life would be primitive, unless there was another power source. In a world with available nuclear power, life would be much more abundant than now. In a world without consciousness, there would be no war. In a world without emotion, there would be no suicide. In a world with no psychology, there would be no madness. In a world without motion, there world be no progress and no death. In a world without causation, there would be only chaos. In a world without necessity, there would be only randomness. In a world without events, everything would be eternal. In a world without the infinite, there would be no finite. In a world without relations, there would be no facts. In a world without facts, there would be nothing. In a world without reality, there would be no unreality. In a world without nothingness, there would be no being.
Counterfactuals are inherently surprising, which is why we are fascinated by them. They tell us how different things could be under small changes. There are many kinds of counterfactual. We live in their shadow. They are always controversial, sometimes paradoxical. They give us a sense of intellectual freedom. They scare us. They are also funny. We wouldn’t know what to do without them. In a world without counterfactuals, there would be no thought worthy of the name…
On the utility– the necessity– of contemplating the unreal: “Counterfactuals.”

As we analyze alternatives, we might recall that it was on this date in 1898 that chemist Morris Travers discovered Krypton– the element (Kr), not the counterfactual planet.
