Taking as its jumping off point recent attempts in the sciences of the mind to facilitate direct brain-to-brain communication, this article considers the challenges such a development poses to the phenomenology of intersubjectivity. This is examined initially through recourse to Husserl's description of the encounter with the other in the Cartesian Meditations, Levinas’ rival account in Totality and Infinity, and Derrida's contribution to this dialogue in the essay ‘Violence and Metaphysics’. All three turn around the problem of how the externality and otherness that constitutes the other qua other can be presented to the I while being maintained in its very externality and otherness. The paper asks whether the prospect of fully realised telepathic communication would overcome intersubjective distance by offering a direct insight into the other's phenomenological interior, and how such a relation is to be conceived using the terms outlined in the above trio of texts. Finally, through appealing to Derrida's enigmatic essay ‘Telepathy’ and offering a close reading of his late concept of teleiopoesis we will overturn the phenomenological terms in which the discussion has so far been framed while arriving at a form of telepathy that is not reducible to the simple communication of a message between an active sender and a passive recipient, but which simultaneously maintains the distance between the actors involved. Teleiopoesis undermines the stable identity of the terms I and other and consequently the very concept of intersubjectivity is put into question.

This essay examines the concept of genius in the work of Jacques Derrida and Immanuel Kant and argues that, despite Derrida’s arguments to the contrary, there is significant space for convergence between the two accounts. This convergence is sought in the complex, paradoxical relationship between the invention of the new and the contextual conditions, or ‘rules’, from which any work of genius must depart but without which no work of genius would be possible. It is my argument that Kant evades the true consequences of his own thought and escapes into a naturalist metaphysics. Only Derrida reveals the aporetic logic at the heart of genius but he fails to recognise the continuity between his own argument and that of his 18th-century predecessor. Derrida’s genius, so I contend, is Kant’s genius pushed to the limit and with all transcendental guarantees removed

This thesis is a response to the increasingly widespread belief in the potential for technology and modern science to enable finite subjects to overcome the essential limitations constitutive of finitude and, hence, subjectivity. It investigates the truth and extent of such claims, taking as its focus quasi-miraculous technological developments in neuroscience, in particular Brain-Computer Interfacing systems and cognitive imaging technologies. The work poses the question of whether such emergent neurotechnologies signal a profound shift beyond receptivity and finitude by effectively bridging the gap between interiority and exteriority. Organised around a quadripartite division, the thesis pursues this idea firstly with regard to the act of artistic creation; secondly through an exegesis of Kant’s account of the original or infinite creativity of the Supreme Being; thirdly through readings of Freud and Jung and their respective models of the psyche; and finally through an interrogation into the possibility of telepathy and the various ways in which it can be conceived. Each chapter thus takes place as an extended thought experiment, exploring the consequences of a seemingly unprecedented proposition that promises to eradicate the finite gap between internal and external. This is followed to the limits of conceivability before asking in each case whether we may in fact need to rethink the very premises around which each proposition has framed the problem.
