  The other source of insecurity is doubts about whether, within Hare’s framework, we are justified in restricting the relevant range of preferences. If, in deciding what ought to be done, I am rationally bound to identify with the agents whose preferences, internal or external, bear on it, how can I fail to take on the widest range of actual preferences, now-for-then as well as now-for-now and then-for-then, external as well as internal, and uninformed as well as informed? Hare inclines this way, writing “It is still my belief that a full account of the matter would assign weight to all preferences” (1981: 103–4). However, how might this best be done? Let us take them in turn.
