Evolution and awareness If I write you a note saying "The cat is on the mat" is the note telling you that the cat is on the mat? No. I am. By means of the note. The note is telling you nothing. I am telling you something by means of the note.
So, in a way, the note and the inky squiggles it has on it, are not representing anything to be the case. I am doing the representing. I am using the inky squiggles to do so, but that doesn't mean that the inky squiggles or the paper on which they're written are doing any representing.
What if the note was the creation of blind natural forces and you just found it on the floor (so it was not being used by an agent to convey information to you, and nor have the squiggles been created by any agent)? Are you now being told that the cat is on the mat? No. You'll think you are. But you're not. For as noted above, neither the note nor the inky markings are themselves doing any representing. In order for the note to have representative contents it needs to either have been created by a mind for the purpose of representing something to be the case, or it needs to be being used by a mind for the purpose of reprsenting something to be the case. Absent this agential input, the note is not really a 'note' at all, just an apparent one - one that you can and will easily mistake for a note.
Nothing changes if, rather than inky notes, we are talking about mental states. Philosophers talk about mental states with representative contents. So, imagine a visual impression of a cat on a mat. Well, it 'represents' the cat to be on the mat. Though, well, it doesn't. The mental state itself is not doing any representing - that's as confused as thinking that the note itself tells you the cat is on the mat. The mental state represents nothing at all unless it was either created by an agent with the express purpose of representing something to you, or is being used by an agent with the express purpose of representing something to you. If neither is true, then the mental state is not representing anything to be the case and is thus incapable of providing you with any kind of perceptual awareness of anything.
So, the visual impression of a cat on the mat is certainly capable of providing one with a perceptual awareness of a cat on a mat. But it won't do so unless it was designed by an agent to provide you with that awareness, or it is being used by an agent to provide you with that awareness.
