 Did I drink the coffee or not? Did I raise the coffee cup to my mouth or not? You will only know if you're empirical, right? So empiricism, it's a tenet in science or it's a method of observation in science. So an empirical method is one of direct observation. So you know that I raised the coffee cup to my mouth. Everybody in the studio audience here knows that I raised the coffee cup to my mouth. However, no one knows but me if I drank it, right? You might see my throat go like that, but that doesn't mean I drank anything, right? It just means that you saw my throat do that stuff. So the point being that empiricism or empirical, being empirical, empiricism is a method of science that allows, is for direct observation. And there is no room for interpretation of what happened. There's no belief, there's no bias. It's just I saw it, I heard it. So scientists that are empirical are extremely strict on what they accept as scientific evidence, right? I hope that makes some sense. It's very important for the field to be empirical.
