I consider it cavilling because we are talking merely about the appropriate term to use to refer to a mechanism that may or may not be capable of generating states of awareness in its possessor.
For an analogy, imagine a faker of banknotes has made a machine for printing notes that are physically indistinguishable from genuine currency. That machine is not printing money. It is printing fake money. What do we call such a machine? Well, that's not a philosophical question and it really doesn't matter when the point that is being made is that this machine - whatever we may call it - is not printing money, even if it is identical, mechanically, to those machines that do print money. For whether a machine is printing money or fake money is not a matter determined solely by how the machine functions or the intrinsic properties of its product, but also its relational properties.
Your analysis of my argument is wrong. Again, using the forging machine above to illustrate: we have a machine that is spitting out notes that are physically indistinguishable from genuine banknotes. Is it printing money? Well, that depends on who made it and who is using it, right? You can't tell from just inspecting and describing the machinery in ever more detail or scrutinizing the notes themselves, for by hypothesis the notes are physically identical.
That's what I am arguing in respect of the faculties that create some of our mental states, namely those by means of which we gain awareness, if gain it we do. Those states are the pieces of paper that the mechanism is producing. To be capable of giving us awareness they need to have 'representative contents'. In this analogy that is equivalent to the property of being a genuine banknote as opposed to a fake. And I am arguing that to have that status, the mental states in question need to have been produced by a mechanism that was designed to give its bearer the contents in question, or is being used to do so. So in the analogy, that would be like saying that the machine that produced the note needs to be being used to do so by some legitimizing government agency.
I am arguing, then, that if our mechanisms of mental state production are the creation of blind evolutionary forces, then the mental states they create in us, though introspectively indiscernible from the genuine article, will be fake and thus will not give us any genuine awareness of anything.
Any why is this? For I have not blankly stated it, but argued for it. Here's why. In order for a mental state to give one an awareness of something, the mental state in question needs to have 'representative contents'. That is, it needs to represent something to be the case. It needs, in effect, to be telling us something.
However- and this is my argument - only minds can make representations. For 'representing' is an activity - an activity of mind. Mental states themselves do not make representations. That is as confused as thinking that thoughts think. Thoughts do not think. Thinkers think (and they think by having thoughts). But thoughts do not themselves 'think'. And likewise, no mental state makes a representation. Minds make representations, but mental states do not.
How, then, can a mental state 'tell us' anything about anything? Well, the same way a note can. A note saying 'close the window' is not itself telling you to close the window. Rather, someone is using the note to convey to you their desire that the window be closed. When that's the case, we may say "the note told me to close the window", but this is not literal: we mean by it that someone told us to close the window by means of the note. Likewise, our mental states cannot literally make representations. But we can talk about them as if they do when they are being used by an agent to make representations.
But if the faculties that generate our mental states - including those we take to have representative contents - are built by blind forces, then the states in question will not have any representative contents. And thus they will be incapable of giving us any awareness of anything, even though our introspective situation will be indiscernible from what it would be if they were genuine representations.
