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)

This research is about altruism. In our first chapter, our quest to find whether we are essentially altruistic starts with questioning particular ways of inquiry and proposes a philosophy of unbracketing. In our second chapter, we realise that our proposal starts with an imperative – a prescription. We begin by meditating on the phenomenon of prescription which seems to precede all ways of inquiry. Our analysis of prescription reveals that altruism is to prescribe oneself towards an Other. This type of (...) prescription is to promise a future for an Other. To promise is to give one’s word and to undertake to realising it. In our third chapter, we explore the act of “giving one’s word.” To give one’s word is beyond a speech act. In fact, it is to give one’s logos. An altruistic attempt is carried out in this chapter to liberate ‘logos’ from particular conceptions and allow for its universal meaning to emerge. Logos is traced back to its inceptual conception as existence or will to power – a will to future. This philosophical excavation leads us to our fourth chapter where we re-encounter our original paradox. That is, while human reality starts with a promise of helping someone to make sense – to understand – we have been trying to understand understanding, or how we make sense, by removing the Other and by focusing only on subjective conditions. In this chapter, we reveal how to understand an Other is an altruistic act. In our final chapter, we carefully observe that human existence is a gift from the Other. We describe this gift as a metaphysical passage from being to existence – an altruistic act. A passage which is created by an Other who promises to give us the means to be able to create meaning, that is to say, to exist. (shrink)
