How neat is the dichotomy between cognitivists and non-cognitivists? Are there significant philosophical factions holding positions such as

• "Murder is wrong" is a statement of belief, but it also expresses an emotion (and morality's peculiar charm comes from appealing both to a person's analytical mind and to their instincts)
• Some people approach morality as a system of beliefs, others as gut reactions, and this is connected to their personalities in interesting ways
• Or perhaps the same person can shift over time from gut reactions to believing in absolute laws to believing that morality is a natural phenomenon, paralleling for example their growth from infant to child to adult

et cetera?
