The consciousness continuum: from "qualia" to "free will".

The consciousness continuum is seen as extending from simple sensory experiences to complex subjective constructions resulting in the apparent exercise of conscious will. The phenomena between these two extremes include spontaneously occurring mental contents, unintended perceptual experiences, memory retrievals, and problem solving including feedback of conscious contents. Two factors describe this continuum: The presence or absence of intention (psychologically defined) and the complexity of the cognitive construction involved. Among other benefits, such an analysis is intended to provide an alternative to metaphysical and vague concepts such as qualia, free will, and intentionality.
