If we consider a behaviour such as speech, the subject will not say that their qualia have changed unless they think that they have changed.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div></div><div>Or at least if there is a set of behavior for a particular 'subjectivity' redness, and a set of behavior for a different subjectivity 'greenness,' if the subjectivity is different the corresponding sets of behaviors for each of those different 'subjectivity' (quale), must be disjoint. In other words any particular set of behavior can't have two different 'subjectivity' (quale).</div></div></blockquote><div dir="auto"><br></div><div dir="auto">Yes, but there is a potential problem here. If we speculate that the subject’s qualia have changed from redness to greenness, but their behaviour does not change because they do not notice a change, then in what sense is it meaningful to say that the qualia have changed?</div></div></div></blockquote><div><br></div><div>Wait, what? We're not talking about the substrate independent layer, were talking about what consciousness is made of: qualia. That which we know (i.e. that which we can notice) is what consciousness is, and this noticeable knowledge is composed of diverse colored qualia.</div><div>We are only talking about qualia being sufficiently different (i.e. redness and greenness) that we can notice such differences. If you can't notice the difference, then that qualia is defined to be in the set that is considered to be that singe quale. It is only a different quale if you can notice that it is different.</div></div></div></blockquote><div dir="auto"><br></div></div><div><div dir="auto">Yes, I agree. If a change in qualia is impossible to notice then it isn’t really a change. It also won’t be associated with a change in behaviour. So if it is noticed, there will be a change in behaviour: “colours look different than they used to”. A corollary of this is that if there is no change in behaviour, there can be no change in qualia.</div></div><div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div class="gmail_quote"><div></div><div>To me, what you are saying is like saying: Despite <b>ALL</b> of our objective measurements and experiences being consistent with the earth being round, and <b>NONE </b>of our objective measurements and experiences being consistent with it being flat, it still could be flat.</div><div><br></div><div>We know the world is round, because of what astronauts in orbit experience and ALL of our objective measurements are consistent with.
