FRATERNAL LOVE

Fraternal love (Prehispanic sculpture from 250–900 A.D., of Huastec origin). Museum of Anthropology in Xalapa, Veracruz, Mexico.Following developments in electrical theories such as Coulomb's law, which showed that positive and negative charges attract, analogs in human life were developed, such as "opposites attract." Over the last century, research on the nature of human mating has generally found this not to be true when it comes to character and personality—people tend to like people similar to themselves

However, in a few unusual and specific domains, such as immune systems, it seems that humans prefer others who are unlike themselves (e.g., with an orthogonal immune system), since this will lead to a baby that has the best of both worlds.[12] In recent years, various human bonding theories have been developed, described in terms of attachments, ties, bonds, and affinities.
Some Western authorities disaggregate into two main components, the altruistic and the narcissistic.

This view is represented in the works of Scott Peck, whose work in the field of appliedsychology explored the definitions of love and evil. Peck maintains that love is a combination of the concern for the spiritual growth of another," and simple narcissism.[13] In combination, love is an ctivity, not simply a feeling.acred Love Versus Profane Love (1602–03) by Giovanni glione.Comparison of scientific modelsBiological models of love tend to see it as a mammalian drive, similar to hunger or thirst

psychology sees love as more of a social and cultural phenomenon. There are probably elements of truth in both views. Certainly love is influenced by hormones (such as oxytocin), eurotrophins (such as NGF), and pheromones, and how people think and behave in love is influenced by their conceptions of love. The conventional view in biology is that there are two major drives in love: sexual attraction and attachment. Attachment between adults is presumed to work on the same principles that lead an infant to become attached to its mother.
