A fine argument for materialism is that the terms we use to describe behaviors and aspects of mind (even 'mind' itself) are derived from 'folk psychology,' in other words ordinary people looking at themselves and creating terms to describe experiences, and passing those terms on through language and culture. They create these terms on the fly, without analysis or basis, from 'feeling' it out, and without thinking twice about the implications of creating a new term; in other words, without actual reasoning to support the use of that particular term. Most of the terms of mind are metaphoric, using pictures to bring the mind to life, to express everyday experiential living. Said folk might defend it by saying we've no better terms, or even no other terms at all, to depict the tragedy of a broken heart or the genius of bright idea. But the materialist, then, is right to say that that doesn't make them real. Promise and courage are actually put together from circumstances. Choice and responsibility are strung on the strings of a tentative thing called "I," to which no one can properly point. We've no better terms to use to describe these things, but then perhaps (in an ideal materialist world) these are things for which more productive terms could be invented to more properly describe them. This would change our relationship to the world and favour the materialist, but perhaps for the better.
I think that it cuts both ways.
Most materialists often do not distinguish between cause and effect and as perpetual bias superimpose one effect after another on the cause. One example is how Theory of Evolution is extrapolated to origin of life and consciousness, without any concrete proof. Another is, how many think that there are machines that have passed Turing's test already and translate that erroneous idea into a belief that machines exhibit consciousness. It is another matter that even if a machine passed Turing's test a conscious agent will be needed to know and certify that.
But this is the very nature of nature -- to enjoy the subject-object division to the hilt.
