In Posthuman Life I define the posthuman in terms of the disconnection thesis (DT). One of the advantages of DT is that it allows us to understand human-posthuman differences without being committed to a “human essence” that posthumans will lack. Rather, we understand the human (or WH, the “wide human”) as an assemblage of biological and non-biological individuals, whose history stretches from the world of Pleistocene hunter-gatherers to the modern, interconnected world, and perhaps beyond. Thus it avoids the accusation that we can render the hypothesis of that there could be posthumans (speculative posthumanism AKA SP) meaningless by denying, or deconstructing the claim that there is a human essence – a set of necessary conditions for being human.
However, DT is in tension with the thought of the radical alien discussed in the preceding post. The problem, again roughly, is that claims about the radical alien seem to imply that the alien is not just difficult to understand – the kind of understanding that could be achieved with time, sweat and ingenuity – but remains beyond human understanding in principle. But this implies that at least one necessary proposition is true of humans – namely that for any radical alien, they would be incapable of understanding it.
Thus there can be radical aliens only if there is (after all) a human essence.
DT does not require that there is no human essence. It is merely consistent with its denial. But I have independent reasons for thinking that there are no necessary cognitive constraints inherent in human understanding. Suppose that there is some kind of human essence and that part of this includes the inability to understand certain radical aliens. It follows that open sentence that the relation term “…. understands R” where R refers to some radical alien, is necessarily false of all humans.
However, this only constitutes a real constraint on humans if each human is necessarily human, that is if there is a necessary limit on the way the cognitive powers of agents could be altered. Maybe there are such limitations, but it seems that either they are knowable a posteriori or a priori. If a posteriori, we need evidence for them. It is not clear that there is such evidence around, or what form it might take. Thus there are reasons for being sceptical here.
Suppose such constraints are the a priori kind buttressed and formulated in transcendental philosophies – e.g. Husserlian phenomenology and some accounts of Kantian philosophy – e.g. the analytical Kantianism associated with thinkers such as Sellars and Brandom.
What these positions have in common is the claim that there are invariant conditions for thought and intelligibility. Here what is at issue is the intelligibility of agents. In the case of phenomenology, the condition is that an agent is embodied in a world shared by humans whose actions and experiences can be understood as directed towards that world. In the case of analytic Kantianism, the condition is similar: the agent’s activity must be interpretable in terms of a set of inferential or practical commitments.
These commitments are social statuses whose content is expressed in the sentences of an interpreting idiom or “metalanguage”. This also presupposes a shared world since this content can only be articulated where enough of the statuses are elicited or prompted by things or states of the world which can be identified by prospective interpreters. In the absence of such referents interpretative idioms would be (as Davidson argues) untestable and lack the non-inferential component required for any plausible inferentialist account of content.
A radical alien would not belong to the set of beings whose agency can – in Davidsons metaphor – be triangulated by reference to a common world. Its agency would be perpetually occult to humans. By the same token it could not belong to the common world of the phenomenological account. It would be a closed book. But here we seemed to be locked in a contradiction.
- The radical alien would not belong to the class of beings whose behaviour can be interpreted as actions.
- The radical alien would be an agent.
- An entity whose behaviours could not be construed as actions, even in principle, would be a non-agent.
After all, where else does our concept of agency get its content than its attribution to the things we could treat as agents in principle?
So 1), 2) and 3) are inconsistent. A paradox! However, we can defuse the paradox by denying 3. 3) implies that a kind of local correlationism for agency. The only kinds of things that could count as agents are those that are amenable to human practices of interpretative understanding, whatever these may amount to. 3) denies the possibility that there could be evidence-transcendent facts about agency such procedures might never uncover.
Have we good reason to drop 3 – other than to avoid the paradox. Yes, I think so – and have argued this at some length elsewhere. We only have to deny that there is some a framework corresponding to the interpretable as such.
And this, of course, is in line with anti-essentialism with regard to the human. If there are no de re modal facts concerning what is possibly (or not-possibly) interpretable, there is no thing such that it is either possibly-interpretable or not possibly-interpretable for us or for creatures relevantly alike. Thus, whatever belongs to the class of agents it is not delineated by any practices of intersubjective interpretation. Another way of putting this is that the concept of agency cannot be totalised. There is no collection of all possible agents.
Thus our concept agent is – in a sense – empty or void. When we speak of agency in the abstract we are not using concepts with which we have an existing, if implicit, mastery. However, it follows that our concept of the radical alien is similarly void. We thought that it must transcend the field of the interpretable. But if, as I’ve suggested, there is no such field, there are no radical aliens if these are understood in the interpretation transcendent sense.
But then what of the intimations of the alien in Lovecraft, Wells and other thinkers? Does my use of idea of the radical alien involve a kind of misprision? In my next post I will argue it does not, but only if we re-interpret the otherness or difference of the alien in aesthetic terms rather than in terms of some metaphysics of agency.
