 (4) Qualia as intrinsic, nonphysical, ineffable properties. Some philosophers (e.g, Dennett 1987, 1991) use the term ‘qualia’ in a still more restricted way so that qualia are intrinsic properties of experiences that are also ineffable, nonphysical, and ‘given’ to their subjects incorrigibly (without the possibility of error). Philosophers who deny that there are qualia sometimes have in mind qualia as the term is used in this more restricted sense (or a similar one). It is also worth mentioning that sometimes the term ‘qualia’ is restricted to sensory experiences by definition, while on other occasions it is allowed that if thoughts and other such cognitive states have phenomenal character, then they also have qualia. Thus, announcements by philosophers who declare themselves opposed to qualia need to be treated with some caution. One can agree that there are no qualia in the last three senses I have explained, while still endorsing qualia in the standard first sense.
