My significant other ate cucumbers and onion with some ranch. I called it a cucumber onion salad. She says there aren’t enough ingredients to call it a salad, because “it takes multiple ingredients”. I pointed out she had three and asked what the minimum is. She refuses to answer so I ask Lemmy.
I know, I was being humorous but it is in fact the way most categorization works. Very seldom is it a taxonomy; the way we recognize faces, voices, shapes, etc … it’s all probabilistic.
