People may have a stronger tie to their native languages
than to the places where they were born; language is a more portable
and powerful tool for expression and learning.
Language, like religion, is a part of a person’s identity,
which no one should try to take away.
Philosphical languages appeared earlier than the first international auxiliary languages,
but their purpose was less to communicate widely and more to organize knowledge.
It turned out to be impossible to organize all human knowledge as a tree structure.
In this mix should also be mentioned many naturalistic zonal constructed languages,
such as Afrihili and Slovio, some of which may be considered international auxiliary languages.
