The basic idea of Esperanto is about tolerance and respect for people of diverse nations and cultures. Communication is indeed the essential part of understanding each other, and if that communication happens through a neutral language, that can help the feeling that we 'meet' on equal grounds and respect for one another.
Important traits of Esperanto
* International: Esperanto is most useful for communicating among people of diverse nations who do not have a common mother tongue.
* Neutral: It doesn't belong to one people or country, so it works as a neutral language.
* Equal: When you use Esperanto, you feel more equal from a linguistic standpoint than when, for example, you speak Spanish with a native Spanish speaker.
* Relatively easy: Thanks to the structure of Esperanto, it's usually much easier to master than other foreign languages.
* Living: Esperanto evolves and lives just like other languages, and it can be used to express the most varied facets of human thought and emotion.
