Abstract

Discussion surrounding first contact with extra-terrestrial intelligence (ETI) is hotly debated in the literature. This paper responds to claims made by Jebari and Olsson-Yaouzis that the ‘dominant thought’ in the philosophy of language indicates that communication with ETI would not be possible, and that the resultant uncertainty forces us into the Hobbesian Trap—the proclivity to adopt pre-emptive military strategies as a function of mutual distrust and fear of imminent attack. The ‘dominant thought’ in the philosophy of language constitutes largely behaviourist thinking and hinges on ‘shared human context.’ However, shared universal contexts, together with the potential existence of post-biological ETI, suggest that communication at a level sufficient to interpret basic dispositions (what I call the level of ‘performative function’) may be possible. Deploying both philosophical and game theoretical analyses, this paper provides several refutations and a repudiation of Jebari and Olsson-Yaouzis's claims: I correct the assumption that ETI would necessarily adopt a game theoretical rationality, critique the notion that ETI would choose a risk-dominant strategy rather than a payoff-dominant strategy, repudiate the claim that communication with ETI would not be possible, and show how the Hobbesian equivalence principle is violated in a proximal first-contact situation. Finally, in the absence of game theoretic decision-making (and inline with the calls from the Billingham report), this paper commences work on the development of an incomplete set of Axioms of First Contact from which to generate a definitive groundwork for both post-detection protocol and rules of engagement. An open invitation to other contributors to criticise, augment, and advance this bottom-up approach to first contact is extended.
