In the positivist tradition, it is common to dissolve certain ideas as being meaningless and not worth further consideration. Roughly, the statements corresponding to those elements of our mental experience that are neither identifiable with verifiable facts nor are derivable using logic are considered nonsense. So, within this framework, we can(if I am not missing anything), classify the contents of our thoughts into meaningful and meaningless aspects. Now, to which of these categories does the statements about 'qualia' fit? Is there no hard problem of consciousness, from a positivist perspective? Consider this statement "I am conscious of the blue sky now". Apparently, this is not a meaningless sentence. So, if it is meaningful how do I verify it. One could say that somebody put me inside an MRI while I am having that experience and show me the brain regions activations corresponding to that experience. Does this count as a verification? If so this verification is of a different kind, for in the usual sense, the verification involves the object about which the experience is based.

    Ironically, the arguments positivists used to argue that certain ideas are meaningless apply to their arguments themselves (they are neither empirical nor analytic), making them meaningless by their own standards. As a result, positivist framework has been largely abandoned since 1950-s, see SEP. To dissolve the "explanatory gap" with consciousness, if it is possible, one would need some new ideas. – Conifold Apr 29 '19 at 4:56
  • It's interesting you pick the colour of the sky as an example. For a long time there was conjecture that the Ancient Greeks couldn't perceive the colour blue. This stems from Homer's description of the sky as 'bronze'. At first you imagine that Homer was employing poetic licence, but it turns out, that the question of whether the Greeks really believed the sky was bronze coloured, has been the subject of a vast amount of scholarly work. – Richard Apr 29 '19 at 13:51

    There is a recent article offering a new concept that can answer the hard problem of consciousness. If you're interested in knowing what it is, you can check it out here. – user287279 May 2 '19 at 4:04
