 One way of responding to this continuing threat is to find an argument for saying that every agent has, at least fundamentally, the same motivations: hence moral reasons, being built upon these motivations, are indeed unconditionally and universally overriding, as the ethical rationalist hoped to show. One way of doing this is the Thomist-Aristotelian way, which grounds the universality of our motivations in our shared nature as human beings, and in certain claims which are taken to be essentially true about humans just as  such.[28]  Another is the Kantian way, which grounds the universality of our motivations in our shared nature as agents, and in certain claims which are taken to be essentially true about agents just as such.
