Loglan ( log ical lan guage) is a planned language developed by James Cooke Brown in the late 1950s .

According to a linguistic theory - the Sapir-Whorf hypothesis - the meaning of a statement depends on the structure of the language: language influences thinking , not the other way around. A culture therefore develops with the language and its limitations. If these restrictions are lifted, individual thinking and the development of cultures should be promoted.

Loglan was designed to test this hypothesis. Brown wanted to investigate whether people who learn a very different language also think very differently. It was therefore important to him that Loglan deviated from natural languages ​​in every respect. A specific feature of this language is that the meaningful words are not differentiated into verbs, nouns, etc. and, above all, that the syntax is structured strictly according to the principles of predicate logic . Loglan was the first logical language .

The language was first described in Scientific American in June 1960 . In 1966 Loglan 1 appeared, a comprehensive description of the language. As computer analysis uncovered syntactic inaccuracies, the language was developed over the years. It wasn't until 1988 that the final loglan appeared. It is basically a speakable language. Although the grammar is simple, it is difficult to actually learn the language.

Since Brown tried to legally restrict the use of the language, many of his followers got together in the 1980s in the Logical Language Group and developed a new, fully usable language called Lojban based on similar principles . After Brown's death in 2000, the followers lost their central figure and an academic authority, which is why the initial Logical Language Institute was sometimes in the disintegration stage. The last adjustment of the grammar and update of the reference works Loglan 4 and Loglan 5 took place in 2016 and a. available as shareware .
