 Okay, well, let's start with Hylis here, right? We've got this fantastic idea, unbelievable idea. The Philanus is gonna tell us that material substance is either absurd or results of skepticism because it's relying upon empiricism. So now we're gonna hear from Hylis, and Hylis is gonna give us these working definitions of sensation and object, right? Sensation and object. And so how does he define each of these? So sensation, Hylis says, is the act of the mind perceiving. Is an act of the mind perceiving, okay. So we can talk about our basic five senses, right? That's a great way to start talking about sensation. The other thing is the object. And the object, according to Hylis, is what is perceived. That's what's perceived. And so what he, so, you know, you give this example, I think it's a tulip, right? Give them an example of a tulip, perceives the colors and everything, and the object is the tulip. That's what's perceived, okay. So Hylis also states that sensations are in the mind only, right, sensations are in the mind only. Sensations are not in the object, they're in the mind. Now, Philanus, at this point, is probably, it's like, okay, sure, keep talking. Because Philanus is setting up a bit of a trap for Hylis in this regard.
