Religious philosophers argue that by helping someone, a person, first of all, helps himself. If help is disinterested, it is conditioned by the inner need of a person, so someone has it, and someone is completely deprived of it. The reasons can be very different.
Man is a social being living among his own kind. Those who find themselves in a difficult situation sometimes find it difficult to do without the help of the people around them. Probably, anyone can find themselves in such a situation. It is then that society, in the person of those who are next to it, extends a helping hand so that a person does not fall. That is, help is a natural manifestation of the struggle to preserve the species. This is if we consider a human being a part of living nature.
Helping other people is also a social responsibility norm. The most striking example is charity, helping those in need or victims of devastating disasters. True, in this case, the norm of social responsibility practically does not work if we consider the person who needs help to be guilty of his misfortunes. If a person deliberately destroys his life, then no one can help him except himself.
A person can also provide assistance, quite pragmatically hoping that in return he will receive more than he gives, or at least an equivalent amount of material or non-material benefits. Such help, although it is, in fact, barter, can be perceived by the participants in the exchange with gratitude. Each of them helped the other to acquire what he did not have. This motive, when help is deliberately provided in the hope of receiving a response, is called "social exchange".
There is a theory of "innate empathy", that is, researchers have confirmed that a person has an innate ability to empathize and empathize. This is more evident in the attitude of the people to whom he is attached. Many people are completely genuinely upset when they see the troubles of others, so they rush to help in order to eliminate the mental discomfort that has arisen. This type of help is perhaps the most disinterested, although partly due to selfishness. But you can't condemn a person for helping others, so that he himself feels good and calm?
