Abstract Usually relegated to a footnote in the historical accounts of planned languages, Sotos Ochando’s Lengua Universal was most likely the first to give rise to a planned language movement. Contrary to later language movements, Sotos Ochando’s had no competing planned language movements to challenge it. Sotos Ochando’s Lengua Universal was also unique in that it was a philosophical language, much like those created in the 17th-century. This article explains the reasons behind the emergence and collapse of this movement. It explores the perceptions of contemporaries regarding the possibility of philosophical language projects, as well as other extralinguistic factors that determined the fate of this movement.

索托斯·奥昌多的语言运动

摘要 索托斯·奥昌多 (Sotos Ochando) 的 Lengua Universal 在计划语言的历史记录中通常被归为脚注，很可能是第一个引发计划语言运动的人。与后来的语言运动相反，Sotos Ochando's 没有竞争性的计划语言运动来挑战它。Sotos Ochando 的 Lengua Universal 也是独一无二的，因为它是一种哲学语言，很像 17 世纪创造的语言。这篇文章解释了这一运动的出现和崩溃背后的原因。它探讨了同时代人对哲学语言项目的可能性的看法，以及决定这一运动命运的其他语言外因素。
