Compassionate Moral Realism (PDF)

Colin Marshall offers a ground-up defense of objective morality, drawing inspiration from a wide range of philosophers, including John Locke, Arthur Schopenhauer, Iris Murdoch, Nel Noddings, and David Lewis. Marshall's core claim is compassion is our capacity to perceive other creatures' pains, pleasures, and desires. Non-compassionate people are therefore perceptually lacking, regardless of how much factual knowledge they might have. Marshall argues that people who
do have this form of compassion thereby fit a familiar paradigm of moral goodness. His argument involves the identification of an epistemic good which Marshall dubs "being in touch". To be in touch with some property of a thing requires experiencing it in a way that reveals that property - that is,
experiencing it as it is in itself. Only compassion, Marshall argues, lets us be in touch with others' motivational mental properties.

This conclusion about compassion has two important metaethical consequences. First, it generates an answer to the question "Why be moral?", which has been a central philosophical concern since Plato. Second, it provides the keystone for a novel form of moral realism. This form of moral realism has a distinctive set of virtues: it is anti-relativist, naturalist, and able to identify a necessary connection between moral representation and motivation. The view also implies that there is an
epistemic asymmetry between virtuous and vicious agents, according to which only morally good people can fully face reality.
