 With this background, we turn to the advantages and disadvantages of the whole-brain approach. First, what considerations favor this approach over the traditional focus on cardiopulmonary function in determining death? The most prominent and arguably the most powerful case for the whole-brain standard appeals to two considerations: (1) the organismic definition of death and (2) an emphasis on the brain's role as the primary integrator of overall bodily functioning. (Some who regard a general definition of death as unnecessary have focused on consideration (2) in defending the whole-brain standard. Some others, as discussed later, have retained consideration (1) but dropped consideration (2).) An additional consideration that has been influential, yet is logically separable from the other two, is (3) the thesis that the whole-brain standard updates, without replacing, the traditional approach to defining death.
