Loglan instance of logical language
Loglan is a logical constructed language originally designed for linguistic research, particularly for investigating the Sapir–Whorf hypothesis. The language was developed beginning in 1955 by Dr. James Cooke Brown with the goal of making a language so different from natural languages that people learning it would think in a different way if the hypothesis were true. In 1960, Scientific American published an article introducing the language. Loglan is the first among, and the main inspiration for, the languages known as logical languages, which also includes Lojban.
Brown founded The Loglan Institute (TLI) to develop the language and other applications of it. He always considered the language an incomplete research project, and although he released many publications about its design, he continued to claim legal restrictions on its use. Because of this, a group of his followers later formed the Logical Language Group to create the language Lojban along the same principles, but with the intention to make it freely available and encourage its use as a real language.
Supporters of Lojban use the term Loglan as a generic term to refer to both their own language and Brown's Loglan, referred to as "TLI Loglan" when in need of disambiguation. Although the non-trademarkability of the term Loglan was eventually upheld by the United States Patent and Trademark Office, many supporters and members of The Loglan Institute find this usage offensive and reserve Loglan for the TLI version of the language.Goals
Loglan (an abbreviation for "logical language") was created to investigate whether people speaking a "logical language" would in some way think more logically, as the Sapir–Whorf hypothesis might predict. The language's grammar is based on predicate logic. The grammar was intended to be small enough to be teachable and manageable, yet complex enough to allow people to think and converse in the language.
Brown intended Loglan to be as culturally neutral as possible and metaphysically parsimonious, which means that obligatory categories are kept to a minimum. An example of an obligatory category in English is the time-tense of verbs, as it is impossible to express a finite verb without also expressing a tense.
Brown also intended the language to be completely regular and unambiguous. Each sentence can be parsed in only one way. Furthermore, the syllabic structure of words was designed so that a sequence of syllables can be separated into words in only one way, even if the word separation is not clear from pauses in speech. It has a small number of phonemes, so that regional "accents" are less likely to produce unintelligible speech. To make the vocabulary easier to learn, words were constructed to have elements in common with related words in the world's eight most widely spoken languages.
