UNIT 6
THE RISE OF LITERACY
Competence with written language, both in reading and writing, is known as
literacy. High levels of literacy are required for using scripts for a wide range of
somewhat specialized functions. When a large number of individuals in a society
are competent in using written language to serve these functions, the whole society
may be referred to as a literate society.
Just as scripts have a history, so, too, does literacy have a history. This
history closely reflects the increasing number of ways in which written materials
have been used and the increasing number of readers who have been able to use
them. Scripts were elaborated to serve new purposes; more importantly, new kinds
of writing systems permitted them to serve a wider range of purposes by a larger
number of individuals.
Although the uses of writing reflect religious, political, and social factors
and hence are not determined simply by orthography, two dimensions of the script
are important in understanding the growth of literacy: learnability and expressive
power. Learnability refers to the ease with which the script can be acquired, and
expressive power refers to the resources of the script for unambiguously expressing
the full range of meanings available in the oral language. These two dimensions
are inversely related to each other. Simple, restricted scripts are readily learned.
Pictographic signs such as those used in “environmental writing” and logographic
scripts with a limited set of characters are easiest to learn and, indeed, are acquired
more or less automatically by children. Syllabaries are reported to be learnable in a
day, or in a few days. Consonantal scripts and alphabets are difficult to learn and
usually require a few years of schooling. Full logographic systems, such as
Chinese, or mixed systems, such as Japanese, are difficult to acquire because they
require the memorization of thousands of distinctive characters. Once learned,
however, they appear to function as well as alphabets.
