Love's place in the spectrum of affect, one of 24 secondary emotions: implications for psychiatry

Love is defined and examined as an emotion, using the psychoevolutionary theory of emotions developed by Robert Plutchik and extended to social psychiatry by Henry Kellerman. This theory posits a fourfold ethogram, representing the valanced adaptive reactions to problems of life which define the eight primary emotions. The problem of identity is addressed by acceptance and disgust; temporality, by joy-happiness and sadness. Using a hierarchical classification system, love is defined as a secondary-level emotion, a mixture of joy and acceptance. Examination of the brain infrastructure of these emotions supports their interpretation as basic emotions. In romantic and other forms of love, there is a global acceptance-incorporation, of the other, together with the joy of sexual pair-bonding. This can rise to the level of a clinical disposition that is both histrionic and manic, akin to a Durkheimian collective effervescence. The emotions of acceptance and joy are in everyday life constrained by ego-defense mechanisms: acceptance is constrained by a more critical, less idealised, view of a potential love object; uninhibited joy of sexuality is defended against by sublimation, in which libidinal energy is deflected into an emphasis on correct and proper behaviour, and purposive and productive activities.
