The Two Camps
Team "Water Is Wet":
Water is the literal definition of wetness. It's the standard by which we measure wet things. How can the essence of wet not be wet itself?
Team "Water Makes Things Wet":
Wetness describes a condition something gains when covered by water. Water can't be wet any more than fire can be burned or light can be illuminated.
The Scientific Perspective
To answer this properly, we need to define "wet."
Possible Definitions:
- "Covered or saturated with water" — By this definition, water molecules are indeed surrounded by other water molecules. So water is wet.
- "The sensation of liquid on a surface" — By this definition, wetness is an experience, a relationship between water and another substance. Water alone isn't wet.
Molecular Reality
At the molecular level:
- Cohesion: Water molecules bond to each other through hydrogen bonds
- Adhesion: Water molecules bond to other surfaces
- Surface tension: Water molecules at the surface behave differently than those below
A single water molecule in isolation can't be "wet"—but can we ever encounter a single molecule?
The Philosophical Angle
- Definitions and language
- Whether properties can be self-referential
- How we categorize the world
The debate continues precisely because there's no single "correct" definition of wet.
The Verdict
- If wet = "covered with water," then yes
- If wet = "the condition caused by water contact," then no
The question is more interesting than its answer. It forces us to examine how we define things we take for granted.
And that's the real value of "Is water wet?"
