The relation of language and mind has interested philosophers for many centuries. 61 ) The Greeks assumed that the structure of language had some connection with the process of thought, which took root in Europe long before people realized how diverse languages could be. Only recently did linguists begin the serious study of languages that were very different from their own. Two anthropologist-linguists, Franz Boas and Edward Sapir, were pioneers in describing many native languages of North and South America during the first half of the twentieth century. 62) We are obliged to them because some of these languages have since vanished, as the peoples who spoke them died out or became assimilated and lost their native languages. Other linguists in the earlier part of this century, however, who were less eager to deal with bizarre data from "exotic" language, were not always so grateful. 63)The newly described languages were often so strikingly different from the well studied languages of Europe and Southeast Asia that some scholars even accused Boas and Sapir of fabricating their data. Native American languages are indeed different, so much so in fact that Navajo could be used by the US military as a code during World War II to send secret messages. Sapir’’s pupil, Benjamin Lee Whorf, continued the study of American Indian languages. 64 ) Being interested in the relationship of language and thought, Whorf developed the idea that the structure of language determines the structure of habitual thought in a society. He reasoned that because it is easier to formulate certain concepts and not others in a given language, the speakers of that language think along one track and not along another. 65 ) Whorf came to believe in a sort of linguistic determinism which, in its strongest form, states that language imprisons the mind, and that the grammatical patterns in a language can produce far-reaching consequences for the culture of a society. Later, this idea became to be known as the Sapir-Whorf hypothesis, but this term is somewhat inappropriate. Although both Sapir and Whorf emphasized the diversity of languages, Sapir himself never explicitly supported the notion of linguistic determinism.

In a world where bad news has become everyday news, people are turning to an ancient technique to deal with stress: meditation. At meditation centers, prayer groups and yoga studios around the United States, more and more are finding peace of mind by being quiet: Some use meditation to help deal with life changes; others, to process the painful reality of political and social unrest around the world of the type that has been experienced more recently. Stress from the September 11 terrorist attacks is "probably about 70 percent" of the reason one Chicago man started meditating and practicing yoga with his new wife. He became so emotionally affected that he realized he needed help in managing his stress. The yoga classes he takes begin and end with meditation. This "quiet time" helps him feel a lot more relaxed and gives him more breath control. The fact is,though ,that he is not alone. Across the country, many are turning to more meditative exercise as they seek both psychological and physiological relief. In addition to helping people work out their stress, these classes bring people together, in the same way that religious services or other community activities have done in the past. Different schools of meditation teach particular techniques, but they share a common basis―focusing attention on something your mind can return to if you are distracted. This may be the rhythm of breathing, an object such as a candle flame loving kindness, or a repetitive movement, as in walking or t’’ai chi (taiji). Regardless of the specific technique or mode that is followed, meditation has well-documented benefits. Medical research indicates that it causes a sharp decrease in metabolic activity, reduced muscle tension, slower breathing, and a shift from faster brainwaves to slower waves. It also reduces high blood pressure. Practitioners are convinced that meditation is good for health because it relaxes the body. For ages, meditation has been a core practice of many groups meeting in their communal or religious centers. However, let’’s not forget that this is the twenty-first century. So, for those people who are too shy or busy to go to the nearest meditation center, there are Internet sites that offer online guided meditation. One has a variety of meditations from various religious traditions. At another, Jesuit priests post meditations and readings from the Scriptures every day, and at still another, Buddhist and Hindu practitioners include music and visuals to accompany their offerings. These websites allow anyone with a computer access to meditation at any time. The fact is that whether online, at Yoga classes, or at local spiritual centers, more people are turning to the practice of meditation. The growing popularity of meditation results from people’’s need for
