This paper takes up the question of whether we can visually represent something as having semantic value. Something has semantic value if it represents some property, thing or concept. An argument is offered that we can represent semantic value based on a variety of number-color synesthesia. This argument is shown to withstand several objections that can be lodged against the popular arguments from phenomenal contrast and from the mundane example of reading.

Gray argues that my three earlier counterexamples fail to refute representational theories of phenomenal character. I maintain that, despite Gray's arguments, each example does in fact work against the particular representational theory at which it is targeted. Further, I question whether my internalism regarding phenomenal character and Gray's externalism regarding modularity are in genuine conflict with one another.

I argue for sensory pluralism. This is the view that there are many forms of sensory interaction and unity, and no single category that classifies them all. In other words, sensory interactions do not form a single natural kind. This view suggests that how we classify sensory systems (and the experiences they generate) partly depends on our explanatory purposes. I begin with a detailed discussion of the issue as it arises for our understanding of thermal perception, followed by a general (...) account and defense of sensory pluralism. (shrink)

Wager has argued that synaesthesia provides material for a counterexample to representational theories of the phenomenal character of experience. He gives a series of three cases based on synaesthesia; he requires the second and third cases to bolster the doubtfulness of the first. Here I further endorse the problematic nature of the first case and then show why the other two cases do not save his argument. I claim that whenever synaesthesia is a credible possibility its phenomenal character can be (...) understood in terms of misrepresentation. (shrink)

In cases where one sense-modality is stimulated by another, we speak of synesthesia, i.e., of a subjective experience of multiple distinct sensations as being quite literally conjoined. The term “synesthesia” is derived indirectly from the Greek words “syn,” meaning “together,” and “aisthesis,” meaning “sensation.” This article focuses on the question of whether synesthesia is in fact a mental disorder or a creative gift. Both the commonsense views that have emerged in recent times, and neurological research, demonstrate that our knowledge of (...) this relatively uncommon phenomenon is slowly but constantly expanding. Proper experimental research conducted with the right sorts of synesthete, and philosophically and scientifically nuanced conceptual studies of synesthesia, can all be helpful when seeking answers to the question posed above, while also confirming general claims about the extent to which our perceptions are really subjective. Most synesthetes see themselves as gifted, and claim that this “conjoining of the senses” enriches the quality of their lives. (shrink)
