Happiness has different meanings for different people.
For behaviorists, happiness is a combination of emotions, and when he/she makes good or positive things, they experience this kind of situation.
For neurologists, happiness is the experience that people have when releasing large amounts of hormones in their brains as a reward for prolonging their life.
According to some religions, happiness is an indicator of the existence of God.
Although many experts have studied the meaning of happiness, philosophers are the only experts who study the problem in more detail. After many studies, philosophers have two basic ideas about what happiness is. The views are hedonia and eudaimonia.
In both, although the two views have found roots in ancient Greek philosophy, although the two views are the most famous.
The hedonistic view defines happiness as the extreme opposite of pain. According to opinion, the existence of happiness usually indicates no pain. Therefore, hedonists believe that the sole purpose of life is to maximize happiness and minimize pain.
For many years, hedonists have come up with ways to make them happy for a long time. Unfortunately, most of the ways are wrong. Some of the wrong ways include: sexual behavior, the use of drugs, alcohol and other things that are social goals and religious contempt.
Eudaimonia's lesser-known view defines happiness as the pursuit of being a better person. Eudaimonists pursue better people by challenging themselves intellectually or by engaging in activities that make them more affluent.
As you can see, the difference between the two viewpoints is that one of the ideas [hedoism] says that happiness comes from the outside, while the other [eudaimonia] says that happiness comes from within.
One can conclude that eudaimonia is a superior view. This is because, in this view, being kind to others, generosity and nurturing talents are often more respected than other pursuits of happiness that often bring happiness. For example, under eudaimonia there is usually no accumulation of health.
Although eudaimonia seems to be a very good point of view, there is a paradox. For example, in order to make you generous to others, don't you need to accumulate some wealth?
It is almost impossible to tell which one is the best perspective of both, and sometimes the best definition of happiness should be left to the individual.
