These are questions we won't even try to engage here. For whatever else the disputants may disagree about, they will almost certainly agree about this: that developing the skills of reading and writing (the first two "R"s) is not only a precondition of being well-educated, but also a precondition of being able to function satisfactorily in a civilized society. Someone who cannot read or write is said to be "illiterate" in a quite strict sense of the word (or perhaps "literacy deprived", if one subscribes - as we shall not - to the passing fads of political correctness). And illiteracy, as we all know, is something to be deplored. It is one of the scourges - along with ignorance, hunger, disease, crime, social and political repression - from which most of us would like to see the world, and elements of our own society, freed.
