>>LOVE!<<

Interpersonal love

Interpersonal love refers to love between human beings. It is a more potent sentiment than a simple liking for another. Unrequited love refers to those feelings of love which are not reciprocated. Interpersonal love is most closely associated with interpersonal relationships. Such love might exist between family members, friends, and couples. There are also a number of psychological disorders related to love, such as erotomania.
Some feelings that are often associated with interpersonal love:

Affection: feelings of tenderness and/or wanting physical closeness
Attachment: satisfying basic emotional needs
Altruism: selfless or unselfish concern for another
Reciprocation: if love is mutual
Commitment: a desire to maintain love
Emotional intimacy: sharing emotions and feelings
Friendship: the spirit between friends
Kinship: family bonds
Passion: whole-hearted desire
Physical intimacy: sharing of intimate personal space
Self-interest: desiring rewards
Service: desire to help
Sexuality can be an important element in determining the shape of a relationship. While sexual attraction often establishes a new bond, sexual intention is considered undesirable or inappropriate in certain love bonds. In many religions and systems of ethics it is considered wrong to act on sexual desire for immediate family, for children, or outside of a committed relationship. However, there are many ways to express passionate love without sex. Affection, emotional intimacy and shared interests and experiences are common in friendships and kinships of all human beings.

Impersonal love

A person can be said to love a country, principle, or goal if they value it greatly and are deeply committed to it. Similarly, compassionate outreach and volunteer workers' 'love' of their cause may be borne not of interpersonal love, but impersonal love coupled with altruism and strong political convictions. People can also 'love' material objects, animals, or activities if they invest themselves in bonding their identity with that item. In these cases, if sexual passion is actually felt, is called paraphilia.

Scientific views

Main article: Love (scientific views)
Throughout history, philosophy and religion have done the most speculation on the phenomenon of love. In the last century, the science of psychology has written a great deal on the subject. In recent years, the sciences of evolutionary psychology, evolutionary biology, anthropology, neuroscience, and biology have added to the understanding of the nature and function of love.

Chemistry of love

Biological models of sex tend to view love as a mammalian drive, much like hunger or thirst. Helen Fisher, a leading expert in the topic of love, divides the experience of love into three partly-overlapping stages: lust, attraction, and attachment. Lust exposes people to others, romantic attraction encourages people to focus their energy on mating, and attachment involves tolerating the spouse long enough to rear a child into infancy.
Lust is the initial passionate sexual desire that promotes mating, and involves the increased release of chemicals such as testosterone and estrogen. These effects rarely last more than a few weeks or months. Attraction is the more individualized and romantic desire for a specific candidate for mating, which develops out of lust as commitment to an individual mate forms. Recent studies in neuroscience have indicated that as people fall in love, the brain consistently releases a certain set of chemicals, including pheromones, dopamine, norepinephrine, and serotonin, which act similar to amphetamines, stimulating the brain's pleasure center and leading to side-effects such as an increased heart rate, loss of appetite and sleep, and an intense feeling of excitement. Research has indicated that this stage generally lasts from one and a half to three years.
Since the lust and attraction stages are both considered temporary, a third stage is needed to account for long-term relationships. Attachment is the bonding which promotes relationships that last for many years, and even decades. Attachment is generally based on commitments such as marriage and children, or on mutual friendship based on things like shared interests. It has been linked to higher levels of the chemicals oxytocin and vasopressin than short-term relationships have.
In 2005, Italian scientists at Pavia University found that a protein molecule known as the nerve growth factor (NGF) has high levels when people first fall in love, but these levels return to as they were after one year. Specifically, four neurotrophin levels, i.e. NGF, BDNF, NT-3, and NT-4, of 58 subjects who had recently fallen in love were compared with levels in a control group who were either single or already engaged in a long-term relationship. The results showed that NGF levels were significantly higher in the subjects in love than as compared to either of the control groups.

Psychology of love

Further information: Human bonding
Psychology depicts love as a cognitive and social phenomenon. Psychologist Robert Sternberg formulated a triangular theory of love and argued that love has three different components: intimacy, commitment, and passion. Intimacy is a form by which two people can share secrets and various details of their personal lives. Intimacy is usually shown in friendships and romantic love affairs. Commitment, on the other hand, is the expectation that the relationship is going to last forever. The last and most common form of love is sexual attraction and passion. Passionate love is shown in infatuation as well as romantic love.
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 like 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 which has the best of both worlds. 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 works in the field of applied psychology 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.In combination, love is an activity, not simply a feeling.

Scientific models

Biological models of love tend to see it as a mammalian drive, just like 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), neurotrophins (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. The traditional psychological view sees love as being a combination of companionate love and passionate love. Passionate love is intense longing, and is often accompanied by physiological arousal (shortness of breath, rapid heart rate). Companionate love is affection and a feeling of intimacy not accompanied by physiological arousal.

Sternberg's Triangular Theory of Love
Main article: triangular theory of love
In the triangular theory of love, love is characterized by three elements: intimacy, passion and commitment. Each of these elements can be present in a relationship, producing the following combinations:

Liking or friendship (intimacy)
Infatuation or limerence (passion)
Empty love (commitment)
Romantic love (intimacy+passion)
Companionate love (intimacy+commitment)
Fatuous love (passion+commitment)
Consummate love (intimacy+passion+commitment)

Love styles

Susan Hendrick and Clyde Hendrick developed a Loves Attitude Scale based on John Alan Lee's theory called Love styles. Lee identified six basic theories that people use in their interpersonal relationships:
Eros (love) — a passionate physical love based on physical appearance
Ludus — love is played as a game; love is playful
Storge — an affectionate love that slowly develops, based on similarity
Pragma — pragmatic love
Mania — highly emotional love; unstable; the stereotype of romantic love
Agape — selfless altruistic love; spiritual
Hendrick and Hendrick found men tend to be more ludic and manic, whereas women tend to be storgic and pragmatic. Relationships based on similar love styles were found to last longer. In 2007, researchers from the University of Pavia led by Dr Enzo Emanuele have provided evidence of a genetic basis for individual variations in Lee's loving styles, with Eros being linked to the dopamine system and Mania to the serotonin system

Love, infatuation, and insanity

"Sacred Love versus Profane Love" by Giovanni Baglione
Studies have shown that brain scans of those in infatuated by love display a resemblance to those with a mental illness. Love creates activity in the same area of the brain that hunger, thirst, and drug cravings create activity in. New love, therefore, could possibly be more physical than emotional. Over time, this reaction to love mellows, and different areas of the brain are activated, primarily ones involving long-term commitments. Dr. Andrew Newberg, a neuroscientist, suggests that this reaction to love is so similar to that of drugs because without love, humanity would die out.

Cultural views

Chinese
In contemporary Chinese language and culture, several terms or root words are used for the concept of "love":
Ai (愛) is used as a verb (e.g. Wo ai ni, "I love you") or as a noun, especially in aiqing (愛情), "love" or "romance." In mainland China since 1949, airen (愛人, originally "lover," or more literally, "love person") is the dominant word for "spouse" (with separate terms for "wife" and "husband" originally being de-emphasized); the word once had a negative connotation, which it retains among many on Taiwan.
Lian (戀) is not generally used alone, but instead as part of such terms as "being in love" (談戀愛, tan lian'ai—also containing ai), "lover" (戀人, lianren) or "homosexuality" (同性戀, tongxinglian).
Qing (情), commonly meaning "feeling" or "emotion," often indicates "love" in several terms. It is contained in the word aiqing (愛情); qingren (情人) is a term for "lover".
In Confucianism, lian is a virtuous benevolent love. Lian should be pursued by all human beings, and reflects a moral life. The Chinese philosopher Mozi developed the concept of ai (愛) in reaction to Confucian lian. Ai, in Mohism, is universal love towards all beings, not just towards friends or family, without regard to reciprocation. Extravagance and offensive war are inimical to ai. Although Mozi's thought was influential, the Confucian lian is how most Chinese conceive of love.
Gănqíng (感情), the feeling of a relationship. A person will express love by building good gănqíng, accomplished through helping or working for another. Emotional attachment toward another person or anything.
Yuanfen (緣份) is a connection of bound destinies. A meaningful relationship is often conceived of as dependent strong yuanfen. It is very similar to serendipity. A similar conceptualization in English is, "They were made for each other," "fate," or "destiny".
Zaolian (Simplified: 早恋, Traditional: 早戀, pinyin: zǎoliàn), literally, "early love," is a contemporary term in frequent use for romantic feelings or attachments among children or adolescents. Zaolian describes both relationships among a teenaged boyfriend and girlfriend, as well as the "crushes" of early adolescence or childhood. The concept essentially indicates a prevalent belief in contemporary Chinese culture that due to the demands of their studies (especially true in the highly competitive educational system of China), youth should not form romantic attachments lest their jeopardize their chances for success in the future. Reports have appeared in Chinese newspapers and other media detailing the prevalence of the phenomenon and its perceived dangers to students and the fears of parents.

Japanese

In Japanese Buddhism, ai (愛) is passionate caring love, and a fundamental desire. It can develop towards either selfishness or selflessness and enlightenment.
Amae (甘え), a Japanese word meaning "indulgent dependence", is part of the child-rearing culture of Japan. Japanese mothers are expected to hug and indulge their children, and children are expected to reward their mothers by clinging and serving. Some sociologists have suggested that Japanese social interactions in later life are modeled on the mother-child amae.

Ancient Greek

Greek distinguishes several different senses in which the word love is used. For example, ancient Greek has the words philia, eros, agape, storge and xenia. However, with Greek as with many other languages, it has been historically difficult to separate the meanings of these words totally. At the same time the ancient Greek text of the Bible has examples of the verb agapo being used with the same meaning as phileo.
Agape (ἀγάπη agápē) means love in modern day Greek. The term s'agapo means I love you in Greek. The word agapo is the verb I love. It generally refers to a "pure", ideal type of love rather than the physical attraction suggested by eros. However, there are some examples of agape used to mean the same as eros. It has also been translated as "love of the soul".
Eros (ἔρως érōs) is passionate love, with sensual desire and longing. The Greek word erota means in love. Plato refined his own definition. Although eros is initially felt for a person, with contemplation it becomes an appreciation of the beauty within that person, or even becomes appreciation of beauty itself. Eros helps the soul recall knowledge of beauty, and contributes to an understanding of spiritual truth. Lovers and philosophers are all inspired to seek truth by eros. Some translations list it as "love of the body".
Philia (φιλία philía), a dispassionate virtuous love, was a concept developed by Aristotle. It includes loyalty to friends, family, and community, and requires virtue, equality and familiarity. Philia is motivated by practical reasons; one or both of the parties benefit from the relationship. Can also mean "love of the mind".
Storge (στοργή storgē) is natural affection, like that felt by parents for offspring.
Xenia (ξενία xenía), hospitality, was an extremely important practice in ancient Greece. It was an almost ritualized friendship formed between a host and their guest, who could previously be strangers. The host fed and provided quarters for the guest, who was only expected to repay with gratitude. The importance of this can be seen throughout Greek mythology, in particular Homer's Iliad and Odyssey.

Ancient Roman (Latin)

The Latin language has several different verbs corresponding to the English word 'love'.
Amare is the basic word for to love, as it still is in Italian today. The Romans used it both in an affectionate sense, as well as in a romantic or sexual sense. From this verb come amans, a lover, amator, 'professional lover', often with the accessory notion of lechery, and amica, 'girlfriend' in the English sense, often as well being applied euphemistically to a prostitute. The corresponding noun is amor, which is also used in the plural form to indicate 'love affairs' or 'sexual adventures'. This same root also produces amicus, 'friend', and amicitia, 'friendship' (often based on mutual advantage, and corresponding sometimes more closely to 'indebtedness' or 'influence'). Cicero wrote a treatise called On Friendship (de Amicitia) which discusses the notion at some length. Ovid wrote a guide to dating called Ars Amatoria (The Art of Lovers), which addresses in depth everything from extramarital affairs to overprotective parents.
Complicating the picture somewhat, Latin sometimes uses amare where English would simply say to like; this notion, however, is much more generally expressed in Latin by placere or delectare, which are used more colloquially, and the latter of which is used frequently in the love poetry of Catullus.
Diligere often has the notion 'to be affectionate for', 'to esteem', and rarely if ever is used of romantic love. This word would be appropriate to describe the friendship of two men. The corresponding noun diligentia, however, has the meaning 'diligence' 'carefulness' and has little semantic overlap with the verb.
Observare is a synonym for 'diligere'; despite the cognate with English, this verb and its corresponding noun 'observantia' often denote 'esteem' or 'affection'.
Caritas is used in Latin translations of the Christian Bible to mean 'charitable love'. This meaning, however, is not found in Classical pagan Roman literature. As it arises from a conflation with a Greek word, there is no corresponding verb.
