In Ancient Greece, the concept of love was divided into 7 constituent elements: agape, phileo, eros, storge, ludus, pragma, mania. And each element is only one side of love, which should not crowd out the others ...


"Agape" means "God's love", or "unconditional love". Agape love is selfless. She gives herself away without expecting anything in return. The sun shines equally on beautiful garden flowers and weeds, because that is the nature of the sun. It cannot but shine.

Agape means to serve another. It is carried out through the will and does not rely on feelings, and is based on choice. When a person makes a choice - to love and follows his decision. This is active, not emotional love. She focuses on deeds, not feelings. Agape is the feeling of love, regardless of whether the object of love is worthy of this feeling. Agape does not set conditions as well as God's unconditional love. This feeling is based on reason and a decisive volitional choice.

Ordinary human love depends on the beauty or positive personality of its object. In contrast, agape does not depend on beauty, it is independent and free.

Human love is based on a sense of need. Feeling her poverty and emptiness, she makes a person become attached to those they need. But, abounding in itself, agape does not feel the need. The apostles said that God loves us not because He needs us, but because He is agape.

Agape lovers do not think about themselves, but about their partners, and what they can do for them. There is more spirituality in this type of relationship than physical intimacy. They are built on selfless dedication ("Darling, I will give everything to you! Be happy, even if not with me!"). Agape is full of sacrifice and self-denial, built on condescension and forgiveness. This love is not for oneself, but for the sake of another. Among the ancient Greeks, agape was considered not only a love feeling, but also the ideal of humane love for one's neighbor, an anticipation of altruistic Christian love.

Agape love is especially important for those who are trying to save their marriage and jointly restore lost love. Of all the aspects of love, agape can be immediately introduced into your marriage life, because it is carried out through the will and does not rely on feelings.

Agape love relationships are strong, true and lasting because they do not depend on physical or sensual love.

A marriage in which agape love exists can go through all the trials! Agape keeps marriage intact when other natural expressions of love are weakened.


Eros is passionate physical love. Love is passion, love is passion. In it, the appearance and physical attractiveness of the partner are of great importance. Relationships develop very quickly. The sex drive is very high. If eros is mutual, then partners are drawn to each other like a magnet. Strong desire for complete physical possession of the partnererom. Eros-ridden lovers sincerely believe they are made for each other.

Eros love is associated with what pleases our physical bodies and caters to our desires. The word "erotica" comes from "eros", which means physical love. Eros refers to a sensual type of love based on self-service and self-satisfaction. Eros wants to get everything for himself. Eros wants to take, not give. Eros can sacrifice the desires and interests of another person in order to satisfy his own.

Eros love depends on the beauty or positive personality of its object. As a rule, we are friends with those who we like. We fall in love with someone who is beautiful, happy, smart and attractive, and we turn our backs on an ugly, weak, ignorant person. In contrast, agape does not depend on beauty or any other positive qualities of its object.

Eros does not mean only one's own sensual pleasures, it also contains the idea of ​​striving to unite with a beloved, desire

to possess it.

Eros is also something romantic, passionate and at the same time sentimental. This is the feeling of love that every person in love experiences. This feeling is sung in poetry, songs are composed about it. It is a sense of admiration, exquisite pleasure. This love is tender, strong, beautiful, and at the same time, painful, because it is an all-consuming feeling.

If a mother loves her child, her love is also often for the most part - eros. The same is the case with the love-dependence of children to their parents, the love of friends for each other, as well as the mutual love of a man and a woman.

In Ancient Greece - Eros was deified, because Eros is stronger than human will. He is the cause of such a miracle as the birth of children. Eros makes families and makes people friends. Eros - contains a powerful force. As something mysterious and powerful, eros was considered in ancient Greece the source of all life. A wave of emotions common to all mankind, eros, like a rushing stream from a destroyed dam, demolishes all the obstacles of human will and wisdom.

Although eros love is a powerful force that draws people to each other, this aspect of love needs help, because such love is changeable and cannot continue by itself throughout life. Eros wants to promise that his relationship will be forever, but on his own he cannot keep that promise.


Phileo is a sensual and tender love. The Greek verb "phileo" refers to affection or friendship in the soul. It is often called "brotherly love". This kind of love is closely related to our feelings and emotions and is the key to falling in love. This kind of love extends far beyond mere physical love, because it penetrates deeply into our feelings. Phileo is a feeling of tenderness towards a lover, but always an expectation of a reciprocal feeling.

Phileo's love manifests itself in sociability with each other, in the exchange of advice, friendship. Phileo creates a sense of inseparable friendship, close relationship. In this kind of love, people share thoughts, feelings, relationships, plans and dreams - the most intimate things they will not share with others. They also spend time together and share common interests. Of course, for full enjoyment in phileo love, the participation of both spouses is required.

A marriage without phileo cannot be satisfactory, even with passionate feelings in the bedroom. Passionate Eros alone in bed is not enough for the relationship to be satisfying and interesting, an exchange of feelings is needed - phileo. Only with the phileo can the marriage be undeniably interesting and rewarding. It is thanks to this love that many get married and hope to live together after that - happily ever after.

The problem with this love is that it focuses on feelings, emotions, and those in turn are unreliable. Many marriages fail because of one unfortunate fact: "I don't love you anymore!" Without agape support, the phileo cannot reliably keep people in relationships when phileo weakens.


Storge is love-affection, which manifests itself as a comfortable, familiar relationship. It consists of natural feelings of disposition and consciousness of belonging to each other. This love is also a feeling that exists between parents and children, or brothers and sisters.

Storge is a calmer feeling than eros or phileo, growing out of affection and friendship based on the similarity of personalities, outlook on life, common interests. It arises gradually - not like an arrow blow, but like a slow ripening of a flower. This is a warm and reliable love-friendship ("Darling, you are my best friend!"). The partner is confident that he will always find understanding and support in his beloved.

Love-storge is like a family hearth - "a place where you are accepted, and you don't need to have merit to come there" (Robert Frost). Storge love in marriage meets our common need to be part of a close circle, part of a family where people care and show genuine devotion to each other. Compared to the attitude

of a cold world, storge love gives us a sense of emotional refuge, consistency and security. Storge is trust itself, it is a patient feeling that implies the ability to wait and forgive.

A marriage lacking such love is like a house with a leaking roof. And where there is a storge, an atmosphere of confidence is created in which all other aspects of love can safely live and develop.


Ludus is a game-like love that is never taken seriously. Although people in love with love, most people do not want to hurt another, nevertheless they often offend their partner. Sometimes they are selfish, because in the first place is their own desire to enjoy this game, and not the thoughts and feelings of another person. Therefore, this type of love is not averse to spinning relationships with several partners at once. Ludus - hedonic lovev-game, not distinguished by the depth of feelings and relatively easily allowing the possibility of betrayal. “I like to play love with everyone,” is her motto.

The one whose love consists solely of this element, as if playing love. His goal is to win, and to win as much as possible, spending as little energy as possible. In lyudus there is neither depth of feelings, nor true devotion, nor anxiety for oneself and a loved one. A person "playing" in love usually seeks brief sensations. He lives for the moment, rarely looks into the future. He has no jealousy, no possessiveness towards his beloved. He does not open his soul to him and does not expect the same from him.

Those who are subordinate to the ludus element in love - want a joyful, light, carefree relationship, they are scared off by a more serious attachment. For them, first of all, their own independence is important. Such a person has an easy attitude to bodily joys: they are not the highest goal for him, but a part of the game, he does not put his soul into them. He is more interested in the enjoyment of the game than the results.

Frivolous people, sometimes can become a prelude to a deeper eros.


Pragma is pragmatic love, realistic and down to earth relationships. They are traditionally called "love of convenience". It's a calm, prudent feeling. If in love-mania feelings reign, subjugating reason, then in pragma reason reigns, and feelings are submissive to him. Here, next to attraction, emotion, passion, there is always a faithful guardian - consciousness.

A true pragmatist will not love someone who is not worthy of love. Love for him is a matter of both the head and the heart.

Pragmatic lovers are often well aware of what they want from a partner, and set him "conditions" that must be met. Love, in which only one element of pragma prevails, is based on commodity-money exchange, on obtaining a certain status, on the exchange of benefits, on the performance of certain duties in relation to each other. For example, a respectable and wealthy man "buys" the love of a young and beautiful woman. And female beauty and youth, in turn, are profitably exchanged for the social status of a man and his economic success.

For pragmatists, a reasonable calculation is very important, and not always selfish, but often everyday. In a family, a pragmatist consciously guides his feelings, can relate well to loved ones: he helps them to reveal themselves, does good, makes life easier. Pragmatists try to plan everything and can, say, postpone marriage before they move to another job, finish their studies, give birth to a child. From the same position, they accept sexual problems. The motto of the pragma is the fullest possible compatibility and responsible attitude towards marriage as a common business.

Pragma does not differ in a variety of emotional shades: they can be rather dull, and really kind and reliable - in this way, pragma is similar to a storga. Pragma attachment has an advantage: over time, the pragma does not weaken and does not cool, buton the contrary, it can become warmer, more sincere.


Mania is love-obsession (from the Greek "mania" - painful passion). Mania -

love-anxiety, love-longing. This is a very emotional love, like riding a roller coaster. Lovers possessed by mania always oscillate between "hell and heaven", between angels and demons, between delight and despair.

This feeling is extremely dangerous, exhausting, draining, carrying an eternal lack of confidence in oneself, in a loved one, jealousy, distrust, it does not endure separation. Such love takes a person captive, subjugates him. Mania is rarely truly happy; it is a pessimistic, self-shattering love, it is nourished by people who lack the energy of bright feelings.

This feeling is usually found in unbalanced people who are turned inward and full of inner discord. Such people usually have low self-esteem, they are often ruled by a feeling of inferiority, hidden or perceived. They are unnecessarily anxious, vulnerable, from this they have psychological breakdowns or sexual difficulties. Lack of self-confidence makes their feelings belligerent, possessive, they can be ruled by painful egocentrism.

This style resembles the "romantic love" stereotype. This is an unbridled passion, an irrational love-obsession, for which insecurity and a huge dependence on the object of attraction are typical ("Beloved, I will die without you!"). This style of love is a major provider of unrequited love suicide statistics. Mania love can also cause broken, painful love-hate.

Let's turn to Google to resolve this issue.

First, it is worth clarifying that pain is caused by nociceptors (from Latin noceo - I damage, I harm) [1], which are involved in the transfer of impulses from a particular places inside or on the body to the central nervous system.

And also to clarify that a lot is a relative concept:

The distribution of nociceptors over the surface of the skin of the face and the mucous membrane of the oral cavity is not uniform. There are zones of maximum and minimum pain sensitivity. The largest number of pain receptors are found in the tissues of the tooth. On the border of enamel and dentin, their number reaches 75,000 per 1 cm², while there are only 200 of them per 1 cm² of skin. It is not surprising that toothache is the most difficult to bear. [2]

The gums, like other parts of the oral mucosa, are richly innervated *, which ensures the reception of various substances and various reflex reactions necessary for chewing, salivation, swallowing and speech. [3]

*> Innervation (from Latin in - in, inside and nervus - nerves) - the supply of organs and tissues with nerves, which ensures their connection with the central nervous system. [4]

As can be seen from the text, teeth have an even greater number of pain receptors, and the gums in general are not unique in terms of the number of these among other mucous membranes of the mouth.

The main function of pain is to protect ... In addition to the fact that the secreted substances from dead cells reach the nocireceptors, they ultimately serve as a "traffic light" that switches to a pathological state and triggers the corresponding reactions - a signaling function. By the way, this is facilitated by the lack of significant adaptability of nociceptors, so you will suffer from almost the same acute pain in the tooth. Well, until it becomes chronic or the cause of the pain is eliminated.

The environment of the mouth is considered opportunistic. In general, the mouth is at the top of the list of the "dirtiest parts of our body." If the conditions of the body change from normal to pathological (disease, inflammation), then this can have a beneficial effect on the development of the flora that exists in the mouth without causing harm in its normal state.

A nerve impulse arising in one of the branches of the nociceptor is directed along the maternal axon to the center. At the same time, it spreads antidromically along the peripheral branches of the axon of the same nociceptor, as a result of which substance P and CGRP are released in the skin. These peptides cause vasodilation and increased capillary permeability. Due to this, the effect of other substances that leave the damaged cells, as well as platelets, mast cells and leukocytes entering the pathological focus, is enhanced. [5]

Although this is a double-edged sword, if the body's signals are ignored or incompetent, dilated blood vessels and increased blood flow will only contribute to the spread of infection.

I suppose whether less pacceptors, then the body would have less information. If in the future a person (as a species or as an individual) has to eat food that is different from the modern understanding or more dangerous / safe for health, then the number and quality of nociceptors will probably change depending on the effect. In addition, so that the body has a more complete understanding of what is being eaten, taste buds are there in a mixture with pain receptors, which also react to chemical stimuli.

I think it is already clear that the main evolutionary the meaning of nociceptors in the gums (as well as pain in general) is protection. Here (link number [6]) even a long article begins with this))).

But here's a curious fact for you,

Through evolution, this defense mechanism was conserved and refined, although the basic function of signaling harmful events remained unchanged. The importance of nociceptors is revealed in rare cases in which children have been born without nociceptors. These children are constantly being injured and often die of complications of minor infections or trauma. Similarly, rats whose nociceptors have been destroyed by neonatal treatment with capsaicin have a short life span and are always bruised and incautious. [7]

People who do not have a feeling of pain due to a congenital defect or a disease of the nervous system are not able to avoid the impact of a damaging factor in time and may become a victim of accident. [8]

which can be taken in two ways. The presence and normal work of nociceptors, as a defense mechanism, and the absence of them or their incorrect work, as natural selection, which leads, among other things, to the death of the individual, making it impossible to continue to develop the genus from him.
