A Theory of Moral Status Based on Reproductive Potentiality and the Dynamic Integrity of Genetic Information: Beings That Must Not Be Killed

Justifying an equal right to life for all human beings while avoiding speciesism remains one of the most persistent and unresolved problems in moral philosophy. Dominant approaches grounding moral status in consciousness, interests in continued existence, or relational value either reintroduce species membership covertly or generate hierarchies among humans themselves. This paper argues that any adequate solution must shift attention away from present mental capacities toward the conditions that make the realization of rational existence possible. It proposes a novel four-condition criterion for determining which beings must not be killed: a being must not be killed if and only if (i) it is currently a rational being, or (ii) it possesses genetic information capable of giving rise to a rational being, where (iii) that information is substantively attributable to the continuous life of this particular living organism, and (iv) the termination of that life would constitute an irreplaceable loss. By grounding moral status in the dynamic integrity and biological individuality of organism-level informational processes, the proposed criterion avoids speciesism while extending equal protection to all living human beings, regardless of current cognitive capacity. The paper thus shows both why the problem is exceptionally difficult and why abandoning it would undermine the coherence of our moral commitments.
