Gumdy,
Part IV Application : Rights for other species?:
Part I defined “interaction,” as it concerns praxeology, as those aspects of the broader concept of interrelating that can uniquely transpire among
actors as opposed to mere behavers, such as animals. Certain animals might be said to interrelate in a sense, but not in a praxeological one. Propositional justification, which is the foundation of the APoA and its justification of the NAP, is a type of communication that humans do not share with animals. It is distinct from other communicative functions found in certain social animals, such as the signaling of threat and subservience in social power relationships. Propositional truth-claiming is the specific realm that, so far as we know, is unique to human beings, and this is the realm from which the APoA springs and to which it applies.
Humans remain capable of communications that are not grounded in truth claims, but in acts of social influence and social signaling. This distinction between influence-focused versus truth-focused communication is a critical one and is transmitted through culture. As Van Dun warns, “teaching children and young adults that they should not ask “Is it true?” but only “What is in it for me?” is abandoning their education in favor of preparing them for recruitment by demagogues” (2009, 5, fn14).
Consent is among the forms of proposition that is invalidated under conditions of aggression. In other words, consent is distinct from acquiescence or surrender. Force may include various “communications” (“Hands up!”), but this type of communication functions as exposed fangs do for wolves, as a threat, not as a statement in the distinctly human sense of words that are to be judged by their truth, internal consistency (lack of performative contradiction) and authenticity.
The classical ad hominem fallacy reminds us of the logical need in discourse to judge statements primarily on their content rather than on the identity of their speaker. From there, it is a short, though perhaps surprising, extension to conjecture that if some as-yet unknown animal or alien species were encountered that proved to be capable of, and actually engaged with humans in, propositional communication, such propositions would likewise logically have to be given priority in judgment over the identity of their speakers. Such a shared foundation could logically form the basis of a cross-species rights framework. This should follow if our foundation for rights does indeed rest in discourse principles and in the sphere of restrictive conditions that the nature of propositional justification entails.
In this context, the idea of a presumption of rationality could also be helpful in considering an expanded definition of personhood: “If a man
proves himself an animal rationis capax [animal capable of reason] by engaging others in argumentation, then he is a person and ought to be regarded and treated as such by other persons” (Van Dun 2009, 9). Members of some newly encountered race may thus at first have to establish through actions their propensity to engage in discourse rather than violence and thereby establish a general presumption of rationality. It is even possible that certain aliens could prove more trustworthy and reliably rational as “persons,” than some fellow humans, as the Vulcans in Star Trek famously dramatized.
The concept of the presumption of rationality also links to the justification of children’s rights. In the case of children—or others who have not actually developed or who have lost through accident propositional discourse abilities—it can be presumed that during a contingent absence of such abilities, they would want to appoint for themselves guardians to employ such abilities on their behalf in protection of their rights. The case for such a presumption is superior to the case for any alternative presumption in the absence of specific contravening evidence.[57]
Go forth and provide this specific contravening evidence that a fetus is not a potential human, and that it is not part of it’s nature.
