“Literacy arouses hopes, not only in society as a whole but also in the individual who is striving for fulfilment, happiness and personal benefit by learning how to read and write. Literacy... means far more than learning how to read and write... The aim is to transmit... knowledge and promote social participation.” UNESCO Institute for Education, Hamburg, Germany
