The 7,400 or so languages in use today speak to the fact that our species is born to communicate. But while it is tempting to view language as merely a consequence of our extraordinary cognitive(认知的)powers, Caleb Everett thinks there may be more going on.
In A Myriad of Tongues: How languages reveal differences in how we think, he argues that language itself may shape our understanding of the world and our experience of time and space. To put it another way, the language we speak may influence the way we think.
Such a provocative(挑衅的)idea might have been controversial(有争议的)a few decades ago, says Everett, because language experts restricted themselves to analyzing languages of industrialized, higher-income countries. But we now know they fall short of representing the variety of languages spoken today-and the more we learn about understudied tongues, the more evidence we find for the complicated interplay between language and thinking.
Take Berinmo, a language of Papua New Guinea, as an example. Unlike English speakers, explains Everett, Berinmo speakers struggle to remember whether an object they were shown earlier was blue or green-perhaps because that language doesn't distinguish between these colours. But it does make a formal distinction between yellowish-greens and other greens, and Berinmo speakers typically find it easy to remember which of these colours an object they saw earlier was painted, while English speakers struggle to do this.
Language also influences how we think about objects. Yucatec Maya, spoken in Mexico, encourages its speakers to classify objects according to their material properties rather than their function. Where an English speaker might group a plastic comb and a wooden comb together and exclude a wooden stick, a Yucatec Maya speaker would usually group the wooden objects together. English-speaking people get the information they need by sight alone.
We live through a language extinction event predicted to see the loss of about 30 per cent of today's tongues by
2100. His book makes it clear this is more than just a tragedy(悲剧)for local communities. Given the insights that languages offer into the human mind, their disappearance is a loss for us all.
