In nature, the notion of a symbiotic relationship is usually understood in terms of the expression “I scratch your back, you scratch mine”; each member performs a beneficial function for the other. But what does ‘beneficial’ mean here? I would like to refrain from answering too quickly “bringing pleasure to” and focus on “helping to survive” to the exclusion of pleasure. Is such a scenario in principle possible?
Is it possible, in other words, that the mutual survival of two species depend on at least one inflicting pain on the other?
Here is what I have considered:
We know that there are an abundance of species in nature who depend on other species in terms of the latter’s typical manner of behaving (i.e. if the latter behaved differently, the former wouldn’t be able to handle them). It is conceivable, therefore, that one species depend on another’s behavior insofar as that behavior is the typical ‘avoidance’ behavior that results from experiences of pain/suffering. For the moment, let’s put aside questions of why such avoidance behavior would be advantage to the former, and just assume that it is (somehow). Then the former species would have an interest in bringing about such avoidance behavior in the latter, and what better way to do so by causing the latter pain and suffering? But of course, the very nature of pain and suffering is such that it signals a condition that warrants the evasion or terminating of that very condition. The ‘victom’ (we’ll call the species that suffers the ‘victom’) has an interest in either evading or terminating the source of the pain/suffering. Thus, the more the ‘assailant’ (we’ll call them that) continues to inflict pain and suffering onto the victon, the more likely the victom will seek out ways to escape the assailant’s assaults, or, to the detriment of the assailant, to eradicate them all together.
Furthermore, pain and suffering are also signals of risk - risk of the failure to survive - thus the warrant to evade the source of pain and suffering or to eliminate it. If, therefore, the assailant continues to inflict pain and suffering, he himself risk losing the victom to the hands of death, that is, losing that very thing on which he depends for his survival.
Such doesn’t look too promising for the assailant in that case - that is, because the infliction of pain/suffering would predictably lead to his own demise - but we are talking about a very complicated process here - that of biological evolution. Is it not conceivable (and conceivability is all we’re talking about here) that the assailant could be resourceful and inventive enough to find ways of keeping the victom alive and functional (so that he continues indefinitely to engage in avoidance behavior in response to pain and suffering) but at the same time readily subject to the frequent infliction of pain and suffering? It would be a very delicate balancing act to be sure, but I don’t see why it would be impossible (at least not in principle - and that is all I’m getting at, keep in mind).
Let’s suppose that this is indeed possible in principle. Would it not follow, therefore, that given enough time (on an evolutionary time scale) the victom would adapt and grow accustome to this way of life such that he may become biologically predisposed to depend on pain and suffering? Is it possible, in other words, that a species not only depend on pain and suffering in order to signal the presence of menacing conditions in his environment, but also to motivate behavior that is essential to his survival? In other words, it is conceivable that we could live a life devoid of pain and suffering, or at least that pain and suffering be minimized to an extremely low frequency and intensity, and still be able to survive (whether or not this is possible practically is another matter), but is it possible that this species we have been considering - the ‘victom’ - be such a species that he depends on a minimally frequent and minimally intense degree of pain/suffering in the way we (or any species) depends on food, air, water, etc. - that is to say, not just to signal the presence of contingent and occasional circumstances that are threatening, but that it is literally impossible to survive unless pain and suffering be experienced as requirements in and of themselves for survival.
To put this question another way - and indeed to return to our scenario of the symbiotic relation between victom and assailant - is it possible for there to be a species that depends for its survival on another species periodically hurting it? One can easily imagine rabbits thriving if there were no foxes, but can one imagine them dying away because of it?
I could understand if there were a whole multitude of exceptions to the scenarios I painted above - those involving victoms and assailants - so I’d prefer not to have to defend those scanerios particularly, but I would like more seriously for this question - is it possible in principle for a species to depend on pain and suffering for its survival - not merely to avoid threating conditions, but to “attract” a certain kind of behavior (avoidance behavior)? - to be addressed and for speculative answered to be suggested.
We have spent the better part of the last few centuries asking the question: can we eliminate the majority of ills mankind suffers from? - and apart from the consideration that we will always suffer ills to one degree or another, and apart from the consideration that we ought to avoid eliminating the feeling of pain by itself at the expense of eliminating its cause (i.e. numbing ourselves despite that the cause of our pain is still present - and so is the threat to our health/survival) - I want to add the consideration whether the very attempt to eliminate pain and suffering could itself be detrimental - that is, in the same vein as, for example, eliminating eating, drinking, breathing.
