Water is wet because the wetter, the better. In other words, "Viscosity."
This is not to be confused with the city of the Visigoths who ended
up ransacking the countryside and pillaging the poor villagers,
and yes, the Village People, too.
Why is water wet? Water is wet so that the fish and other ocean,
lake and river creatures can move through it with fluent ease. Friction
is not your friend when you are trying to move. We need to be able
to drink. We need for boats not to sink. We need for our plumbing
to work. This is why water is wet.
But, really, why is water wet? Water is wet because our sensations
say it is so. We feel wetness. We get out of a pool and we are dripping,
uh, you know. We take a shower and we're, um, you know again.
The question of why is water wet cannot be answered with regular
science methodology, but can be answered in Zen Physics. Water is
wet because this is the nature of water. The nature of rock is to
be hard. The nature of grass
is to be green. The nature of water is to be wet. To take away from
its true nature is to destroy what is and thus water is not water
anymore. It may be ice, but it surely is not water. Water begets
wetness. Wetness begets slipperiness. Slipperiness begets falling.
Falling begets a long and painful hospital stay.
