CBDTE-analysis of the fortunes-of-others emotions: Pity
Des(¬ Fo)
Bel(Fo)
Pity(Fo)
New information
BDC
e. g., Fo = Karl (o) loses his job (F)
Bel(Fo ist bad for o, or¬ Fo is good for o)
Des(good things/no badthings happen
to o [within limits])
1 Pity is a form of unhappiness
2 One is unhappy about the fate of another, Fo
4 Des(¬ Fo) ist derived from a desire for o's welfare
3 One desires ¬ Fo, because one believes that Fo is bad for o
e. g.: Fo frustrates a desire of oo suffers emotionally from FoFo decreases o's well-being
5 This desire is altruistic

CBDTE-analysis of the norm-based emotions: Guilt
Des(¬ Aa)
Bel(Aa)
Guilt(Aa)
New information
BDC
e. g. Aa = Maria (a) lied-to-her-friend-Berta (A)
Bel(a is in situation S anda is an agent of type T)
Des(in S, agents of type T do not perform actions of type A)
1 Guilt is a form of unhappiness
2 One is unhappy about an own action
3 Des(¬ Aa) is derived from the desire to obey a behavioral rule
4Desire to obey behavioral rule is derived from desire to obey P's commandments (= Norm internalization)
Bel(in S, actions of type A are forbidden for agents of type T by P)
Des(obey the commandments of P) 5 Desire to obey P's commandments is not egoistic

Pity and guilt: Distinctive hedonic qualities?
Do pity and guilt distinct have a distinctive hedonic quality? Are the separate forms of displeasure feelings?Introspection suggests 'yes' to meAn argument from self-knowledge of emotions:
Assume CBDTE analysis of pity is correct.Assume we infer emotions from their cognitive and motivational context.Then to know that we feel pity, we must infer that we experience mental pain caused by the frustration of an altruistic desire implausible
Alternative: The displeasure of pity feels in a special, distinctive way. That's how we know what we feel pity (with some experience).

Evolutionary functions of the social emotions I
Organismic (system-internal) evolutionary functions of emotions:
emotions signal congruence or incongruence between newly acquired beliefs and existing beliefs or desiresglobally prepare the cognitive system (or agent) to deal with belief-desire (mis)matches
Hedonic mechanism acts as a motivational support system
Creates an auxiliary desire to reduce or abolish the displeasure caused by a threat to, or a frustration of, the primary desire
hedonistic desire reinforces the primary desire even though it is blind to the aim of the primary desire

Evolutionary functions of the social emotions II
A social-communicative function?Verbal or nonverbal communication of emotion informs other agents about the occurrence of a belief-belief or belief-desire match or mismatch in the agentAlerts other agents to two changes:
The agent acquired a new belief that matched or mismatched a pre-existing belief or desireSomething may have occurred in the world that caused at least this agent to experience a belief-belief or belief-desire match or mismatch.
This information is useful for other agents:Allows them to update their mental model of the emotion experiencer, or of the environment, and thereby better adapt to either.

Evolutionary functions of social emotions II
What are the advantages for the communicator?Communicating emotion increases the agent's predicability and exploitability by others, and gives away useful information for free
readiness to (truthfully) communicate emotions is a form of biological altruisim
possible evolutionary: kin selection, reciprocal altruism, group selection(Richerson & Boyd, 2005), costly signalling (Desalles, 2007)
My proposal for the social emotions: group selectionGroups in which social emotions are truthfully communicated are at an advantage over groups in they are hidden or faked.
involuntary signals of social (and possibly other) emotions may have been selected as truthful signs of other’s group-centered concerns: Their altruistic concern for others, and their true caring for the obeyance of social norms.
