[...] there is no grouping of their working together, which is able to generate things we know as qualia [...]
How do you know this? This is the core of your argument but you fail to present objective reasons for it. Apart from the fact that you switch from the emergence of consciousness to the generation of qualia (about which there is dissent among scientists and philosophers of science as to whether they actually exist), you make the mistake of stating as fact the object of your own incredulity.
Let's look at some real
- you are conscious;
- your brain is a physical object;
- some physical and/or chemical causes influencing your brain can alter your conscious experience;
- a physical blow to the head can render you unconscious.
In short, consciousness has all the hallmarks of being rooted in physical causes. The details of how it happens may still be sketchy, but we have ample reason to suspect that consciousness is an emergent property of the workings of the brain.
William Thomson, also called Lord Kelvin, the pre-eminent scientist of the late 19th century, is known to have promulgated that heavier-than-air flying machines are impossible. Your statement is reminiscent of this mistaken certitude. An apt reply to it would be what Darwin said in the quote below, which I have used for many years as my signature quote on this site, and which has proven wonderfully pertinent to many a discussion here.
