Moral Perception (Vetlesen)
Vetlesen's thesis that the capacity to see what ethically matters depends not on reason but on the capacity to be affected — a developed faculty constituted by exposure to vulnerability, difficulty, and the otherness of what resists.
Moral perception, in Vetlesen's 1994 formulation, is the foundational stage of moral life: before judgment, before action, there must be the perception of moral salience. This perception is not a cognitive operation but an emotional-phenomenological one, constituted by empathy and by the willingness to be moved by what the world presents. Strip away the emotional engagement and what remains is not a more efficient moral agent but an agent who cannot see what matters — no matter how sophisticated their cognitive apparatus. The claim rewires the AI discourse: a technology that produces superior simulations of empathic response without the vulnerability that gives empathy its moral weight is not advancing moral life but attenuating the faculty on which moral life depends.
