Usually such policy makes clear the legal basis for action, identifies the relevant threshold for the use of lethal force and identifies relevant factors which have to be carefully weighed before force is used.
On how to understand the relevant threshold see Section 4 below.
To reduce such presumed undetected antibody activity below clinically relevant threshold levels peritransplant apheresis was indicated [42].
However, such a view depends upon our being able to specify the relevant threshold of intergenerational harm in a different way.
In applying this notion of harm, we compare the values of "having a sufficiently good life" and "having a life that falls below the relevant threshold".
It thus seems plausible to reject the idea that the priority view as such specifies the relevant threshold of intergenerational harm.
In claiming that people should refrain from having children out of regard for the children, when the children can be expected to have a life that falls below the relevant threshold, we rely on our being able to define what it means to be in a state below the relevant threshold and to judge when lives are in that state.
Once the current self falls below the relevant threshold of capacity, she is incapable of generating her own independent interests, and, despite superficial appearances to the contrary, her fundamental interests are really defined by the earlier self.
Ronald Dworkin's influential work defends the capacity for autonomy as the relevant threshold, with autonomy interpreted as "the ability to act out of genuine preference or character or conviction or a sense of self" (Dworkin 1993, 225).
In defining the relevant threshold of harm we may also rely on considerations that reflect the significance of relative differences among future people or people who belong to different generations including the currently living.
Remembering that for the threshold deontologist, consequentialist reasons may still determine right action even in areas governed by agent-relative obligations or permissions, once the level of bad consequences crosses the relevant threshold (Moore 2012).
