There is good reason to believe that the capacity to represent the intentions and experiences of others is deeply dependent on human symbolic capacity. This is because it is a difficult cognitive task. It involves generating something like a simulation of oneself in different circumstances (i.e., projected from another individual’s point of view), and it must include the emotional experiences this would invoke as well. This representation is perhaps supported by recall of images from analogous past experiences, juxtaposed against the images and emotions of current experience. But the salience of direct experience, especially one’s current emotional state, poses a difficult impediment to simultaneously representing the perspective of this other simulated emotional experience. Holding such mutually contradictory representations in mind at once is a difficult task, even when there is little emotion involved, but it becomes deeply challenging when the exclusive states are heavily emotion-laden.
All such cognitive tasks depend critically on the prefrontal lobes of the cerebral cortex. This brain region is essential to any mental process that requires holding the traces of alternative associations and behavioral options in mind to be compared, so that one can act with respect to likely consequences and not merely with respect to their general reinforcement value or their stimulus salience. Reduction of such stimulus drives allows the most effective sampling of options. It is suggested that the prefrontal lobes are disproportionately enlarged in human brains as an evolutionary adaptation to the demands imposed by symbol learning and use. The indirectness of symbolic reference demands a shift of attention away from immediately associated features and to the relational logic behind the symbols, which binds them into a system. So this neuro-anatomical divergence from the ancestral condition likely contributes to the capacity and perhaps even a predisposition to generate the “simulations” required for the representation of others’ experiences.

But it is the referential displacement provided by symbols themselves that is probably critical to reducing the differential in salience of competing emotional state representations to make this mental comparison possible. Studies with primates and children have shown, for example, that failures to make optimal choices when highly arousing stimuli (e.g., candy) are presented can be overcome by substituting representations for the actual thing. By a somewhat ironic logic, then, it may be the capacity to use representations to reduce the emotional salience of particular experiences that has enabled the development of intersubjective empathic abilities.
Symbolic reference also provides a critical support for an additional element of ethical cognition: the need to project forward the consequences of different possible alternative actions. Projecting the plausible physical consequences with respect to one’s own needs and desires is difficult enough, but simultaneously projecting the likely affect on another’s experience is doubly complicated. This is the mental equivalent of running simulations of the effects of simulated actions on simulated emotions, all in conflict with current experiences and emotional states. As the numbers of potentially interfering images and the intensities of the potentially conflicting emotions increase, the importance of symbolic support grows. For this reason, not only do we recognize that young children have difficulty performing anything beyond simple moral assessments, but all cultures actively provide narrative and ritual exemplars for guiding its members in handling ethical matters. The symbolic traditions that constitute cultures almost universally transmit the expectation that one is responsible for considering experiential consequences for others before acting—a moral imperative. Of course, it is also this capacity for imagining the experiences of others that makes possible the most heinous of human acts, such as extortion and torture. The emergence of good and evil are not, then, just mythically linked. Both are implicit in the symbolic transfiguration of emotional experience and the gift of intersubjectivity that results.
