As a society advances, people lead richer lives than before. So, could you say people are happier than before? It is reality that the world is materially richer than before, but people are becoming despondent. At the same time, many kinds of mental illness have become widespread, and people believe that mental illness is the primary reason for suicide. However, I`ll start to talk about suicide from a social point of view.
Émile Durkheim, a sociologist from France, sociologically described suicide in his book, Le suicide. He said suicide is clearly a social phenomenon, and the cause of suicide is also social. In other words, suicide can be defined as "The Death, of the society, By the society, and For the society". If you look at the original causes of suicide, we can realize that many kinds of causes are related with relationships. Also, the thing that makes and defines relationships between people is society. Suicide, which is against instinct for survival, is possible because humans are social animals. Ultimately, suicide is social death.
