. Love directs everything that occurs, in the realm of the gods as well as that of humans (186a-b).

Eyrximachus reasons that when various opposing elements such as wet and dry are "animated by the proper species of Love, they are in harmony with one another... But when the sort of Love that is crude and impulsive controls the seasons, he brings death and destruction" (188a). Because it is love that guides the relations between these sets of opposites throughout existence, in every case it is the higher form of love that brings harmony and cleaves toward the good, whereas the impulsive vulgar love creates disharmony.

Plato concludes that the highest form of love is the greatest. When love "is directed, in temperance and justice, towards the good, whether in heaven or on earth: happiness and good fortune, the bonds of human society, concord with the gods above- all these are among his gifts" (188d).

In the 1660s, the Dutch philosopher Spinoza wrote, in his Ethics of Human Bondage or the Strength of the Emotions, that the term "bondage" relates to the human infirmity in moderating and checking the emotions. That is, according to Spinoza, "when a man is prey to his emotions, he is not his own master, but lies at the mercy of fortune."

Limerent bond

According to limerence theory, positioned in 1979 by psychologist Dorothy Tennov
Dorothy Tennov

Dorothy Tennov was an United States psychologist who, in her 1979 book Love and Limerence ? the Experience of Being in Love introduced the term "limerence"....
, a certain percentage of couples may go through what is called a limerent reaction, in which one or both of the pair may experience a state of passion mixed with continuous intrusive thinking, fear of rejection, and hope. Hence, with all human romantic relationships, one of three varieties of bonds may form, defined over a set duration of time, in relation to the experience or non-experience of limerence:
  1. Affectional bond: define relationships in which neither partner is limerent.
  2. Limerent-Nonlimerent bond: define relationships in which one partner is limerent.
  3. Limerent-Limerent bond: define relationships in which both partners are limerent.
The constitution of these bonds may vary over the course of the relationship, in ways that may either increase or decrease the intensity of the limerence
Limerence

Limerence refers to an involuntary cognitive and emotional state of intense romantic desire for another person. The term was coined by psychologist Dorothy Tennov to describe the ultimate, near-obsessional form of romantic love....
. The basis and interesting characteristic of this delineation made by Tennov, is that based on her research and interviews with over 500 people, all human bonded relationships can be divided into three varieties being defined by the amount of limerence or non-limerence each partner contributes to the relationship.

Parental bonding


Attachment

John Bowlby

 published the ground-breaking paper "the Nature of the Child's Tie to his Mother", in which the precursory concepts of "attachment theory

" were developed. This included the development of the concept of the affectional bond, sometimes referred to as the emotional bond, which is based on the universal tendency for humans to attach, i.e. to seek closeness to another person and to feel secure when that person is present. Attachment theory has some of its origins in the observation of and experiments with animals, but is also based on observations of children who had missed typical experiences of adult care. Much of the early research on attachment in humans was done by John Bowlby and his associates. Bowlby proposed that babies have an inbuilt need from birth to make emotional attachments, i.e. bonds, because this increases the chances of survival by ensuring that they receive the care they need.

Maternal bonding

Of all human bonds, the maternal bond is considered to be one of the strongest. The maternal bond begins to develop during pregnancy; following pregnancy, the production of oxytocin

 and theoretically fostering bonding. It is generally understood that maternal oxytocin circulation can predispose some mammals to show caregiving behavior in response to young of their species.

Breastfeeding

Breastfeeding is the feeding of an infant or young child with breast milk directly from human breasts rather than from a baby bottle or other container....
 has been reported to foster the early post-partum maternal bond, via touch, response, and mutual gazing.. Extensive claims for the effect of breastfeeding were made in the 1930s by Margaret Ribble, a champion of "infant rights" , but were rejected on scientific grounds. . The claimed effect is not universal, and bottle-feeding mothers are generally appropriately concerned with their babies. It is difficult to determine the extent of causality due to a number of confounding variables, such as the varied reasons families choose different feeding methods. Many believe that early bonding ideally increases response and sensitivity to the child's needs, bolstering the quality of the mother-baby relationship – however, many exceptions can be found of highly successful mother-baby bonds, even though early breastfeeding did not occur, such as with premature infants who may lack the necessary sucking strength to successfully breastfeed.

Paternal bonding

In contrast to the maternal bond, paternal bonds tend to vary greatly over the span of a child’s development in terms of both strength and stability. In fact, many children now grow up in fatherless households and do not experience a paternal bond at all. In general, paternal bonding is more dominant later in a child’s life after language develops. Fathers may be more influential in play-interactions as opposed to nurturance-interactions. Father-child bonds also tend to develop with respect to topics such as political views or money, whereas mother-child bonds tend to develop in relation to topics such as religious views or general outlooks on life.

In 2003, researcher from Northwestern University in Illinois found that progesterone

, a hormone more usually associated with pregnancy and maternal bonding, may also control the way men react towards their children. Specifically, they found that a lack of progesterone reduced aggressive behaviour in male mice and stimulated them to act in a fatherly way towards their offspring.

Human-animal bonding


Man and Dog
The human-animal bond can be defined as a connection between people and animals, domestic or wild; be it a cat as a pet or birds outside one’s window. Research into the nature and merit of the human animal bond began in the late 1700s when, in York, England, the Society of Friends established the The Retreat
The Retreat

The Retreat, commonly known as the York Retreat, is a place in England for the treatment of people with mental disorders. Located in Lamel Hill in York, it operates as a Non-profit organization Charitable trust....
 to provide humane treatment for the mentally ill. By having patients care for the many farm animals on the estate, society officials theorized that the combination of animal contact plus productive work would facilitate the patients’ rehabilitation. In the 1870s in Paris, a French surgeon had patients with neurological disorders ride horses. The patients were found to have improved their motor control and balance and were less likely to suffer bouts of depression.

In the 19th century, in Bielefeld, Germany, epileptic patients were given the prescription to spend time each day taking care of cats and dogs. The contact with the animals was found to reduce the occurrence of seizures. In 1980, a team of scientists at the University of Pennsylvania

 found that human to animal contact was found to reduce the physiological characteristics of stress; specifically, lowered levels of blood pressure, heart rate, respiratory rate, anxiety, and tension were all found to correlate positively with human pet bonding.

Historically, animals were domesticated for functional use; for example, dogs for herding and tracking, and cats for killing mice or rats. Today, in Western societies, their function is primarily a bonding function. For example, current studies show that 60–80% of dogs sleep with their owners at night in the bedroom, either in or on the bed. Moreover, in the past the majority of cats were kept outside (barn cats) whereas today most cats are kept indoors (housecats) and considered part of the family. Presently, in the US, for example, 1.2 billion animals are kept as pets, primarily for bonding purposes. In addition, as of 1995 there were over 30 research institutions looking into the potential benefits of the human animal bond.

Because our close friends tend to move in the same circles that we do, the information they receive overlaps considerably with what we already know. Acquaintances, by contrast, know people that we do not, and thus receive more novel information.

Debonding and loss

In 1976, sociologist Diane Vaughan proposed an “uncoupling theory”, where, during the dynamics of relationship breakup, there exists "turning point", only noted in hindsight, followed by transition period in which one partner unconsciously knows the relationship is going to end, but holds on to it for an extended period, sometimes for a number of years.
