A commodity is defined by the ease with which it can be exchanged for something else and can move from place to in search for higher and higher returns. The exchangeability and mobility of commodity is the function of it's independence from all historical and social/cultural contexts in determining it's value. The value of commodity, in other words, is not bound by the context of tradition or culture. Knowledge, however, is grounded in tradition and education properly understood is education of tradition. And hence when one goes abroad for higher education one goes not to acquire disembodied theoretical knowledge but to gain knowledge of and learn from a different tradition. When knowledge is uprooted from tradition that is it's proper context and where it's roots are continuously nurtured and fed by cherished habits of mind that took ages to grow and develop we have only transferable skills. Those who think that knowledge can be easily uprooted and transferred to a new abode also think that education consists of easily identifiable elements. But once we acknowledge that both education and knowledge are grounded in tradition then we cannot but recognize that education is a mixed bag of knowledge, practice, habits of mind and several intangibles that cannot be easily identified and isolated from the tradition of which they are a part.
