I think water has to be wet as a consequence of contradiction. The evidence for this comes in two primary ways. One is due to the way properties are spread, and the other is due to the contradiction of competing properties.
In the first part, we have examples of objects that don't need to carry the properties they spread in order to spread them. But there are also objects that spread properties because they carry those properties. This means that water can fit in either one. If we say each option has a 50/50 chance of being correct we do not get any closer to the truth, we just learn about the two possible answers.
The second part shows us which one is most likely. We don't seem to ever have dry water. The closest thing we may get to dry water is steam, but this is weird to suggest as steam still makes things wet. Fire is complementary to water, yet we can't have wet fire. The reason for this is likely because of the laws of contradiction: an object cannot carry a property and also the reverse property at the same time. I cannot be on fire but not on fire at the same time, and fire cannot be wet. So unless we have examples of dry water, then water must be wet because the law of contradiction suggests that the reason it cannot be dry is that it already carries the property of wetness.
Also fuck you for doing metaphysics in the morning. I'm gonna be questioning life all day now.
