I discuss Descartes’ metaphysics of selfhood, and relevant parts of contemporary philosophy regarding the first person. My two main concerns are the controversy that surrounds Descartes’ conception of conscientia, mistranslated as ‘consciousness’, and his conception of selfhood and its essential connection to conscientia. ‘I’-thoughts give rise to the most challenging philosophical questions. An answer to the questions concerning the peculiarities of the first person, self-identification and self-ascription, is to be found in Descartes’ notion of conscientia. His conception of selfhood insightfully (...) informs his conception of personhood. I offer a unified account of selfhood, conscientia, the first person, and personhood anchored in the self’s authority of reason and autonomy of freedom. (shrink)

Current debates on human rationality are divided between what Matthew Boyle calls the additive and transformative approaches. My concern is not with the current debate, but with Boyle’s alignment of Descartes and Aristotle with the modern approaches, directing his criticisms against the former, and his defence in support of the latter. What motivates my enquiry is whether Boyle’s use of the two philosophers’ theses stands up to scrutiny and consequently whether his alignments are cogent. I focus primarily on Descartes’ position, (...) examining Boyle’s criticisms. Towards the end, I turn to Aristotle’s position and raise two central questions omitted by Boyle. (shrink)
