Nagel’s challenge is to devise an objective phenomenological vocabulary that can describe the objective structural similarities between aural and visual perception. My contention is that Charles Sanders Peirce’s little studied and less understood phenomenological vocabulary makes a significant contribution to meeting this challenge. I employ Peirce’s phenomenology to identify the structural isomorphism between seeing a scarlet red and hearing a trumpet’s blare. I begin by distinguishing between the vividness of an experience and the intensity of a quality. I proceed to (...) identify further points of structural isomorphism (a) between the experience of seeing a scarlet red and of hearing a trumpet blare and (b) between the qualities of those experiences. Lastly, I gesture towards how these distinctions can be an aid in describing what it is like to be a bat. (shrink)

Charles S. Peirce’s semeiotic—his theory about signs, reference, interpretation, meaning, and communication—is applicable with illuminating results to innumerable processes of semeiosis or sign interpretation. Robert C. Neville is the first deep student of Peirce’s semeiotic to have systematically applied that theory to the analysis and theory of theological signs, interpretation, and truth—hereafter, theological semeiotic. The result is easily the deepest and richest theological semeiotic currently available. Being the best, it is also most worthy of critique. In this essay, I argue (...) that Neville misinterprets Peirce’s concept of an index, conceiving an index in terms of the interpreter-object rather than... (shrink)
