As this thread is in the Science board, are we taking the philosophical view that we need to use the tools of science to argue for or against, e.g. an epistemological naturalist perspective (knowledge is best/ (only)? gained via the methods of science/ natural science?.
We have seen arguments that the mind is an emergent property of a complex structure - the brain - and the mind cannot be reduced to physicality in itself. Where the mind relates to subjective experiences, how is it possible for science/ methods of natural science to observe, define or prove anyone's subjective experiences?
Gordon's thread looked into this issue;
http://www.religionethics.co.uk/index.php?topic=20013.0 i.e. that a human mind cannot observe/ know the subjective experience of being a bat.
This discussion between 2 bioethicists, Alex McKeown and David Lawrence, on defining 'mind' and what we mean by the term 'body' (whatever supposedly enables human cognition) and whether the body has much to do with the function of the mind is interesting.
For example, Lawrence seems to suggest that for there to be a mind the brain requires information and information is an ontologically separate fundamental property of the universe. The idea that there is information that we are aware of and our mind processes subjectively but the subjective outcome is something we cannot convey to others, makes sense to me.

Subjective experience is clearly a very important part of being human and impacts on human interaction and socialisation so not surprising that conventions and rules around incorporating subjectivity into society are up for discussion and debate.
