 In this section, we will discuss what having FMS amounts to – a notion key to many non-utilitarian accounts of moral status. With respect to this highest degree of moral status, the literature is the most developed and detailed. Those with FMS are often called “moral persons.” Standardly, FMS is understood to involve (i) a very stringent moral presumption against interfering with the being in various ways – destroying the being, experimenting upon it, directly causing its suffering, etc. While the strong presumption against interfering is the main aspect of FMS, some philosophers include as part of FMS (ii) a strong, but not necessarily stringent, reason to aid and (iii) a strong reason to treat fairly. Since there is no higher moral status, all beings with FMS are owed the same protections and entitlements. That is, all beings with FMS have equal moral status (see the entry on  egalitarianism).
