"By instructing students how to learn, unlearn and relearn, a powerful new dimension can be added to education…Tomorrow's illiterate will not be the man who can't read; he will be the man who has not learned how to learn."
Technically, there are problems with this statement. For example, those who cannot read in the 21st century are still illiterate. But Toffler's claim suggests that a person with obsolete knowledge has just as much a disadvantage as a person who cannot read. Maybe more so.
The learn, unlearn, relearn paradigm explains not only how we improve by adapting to rapidly changing knowledge and understanding, but also how we improve by converting to different ways of thinking and believing.
Everyone in the world has learned, from a young age, a framework for understanding the world. They learn language, customs, culture, and values, often (but not always) within a particular religious context.
As we mature, we learn new things that force us into a choice: we can incorporate new things into our existing framework, or we can unlearn that framework to adapt to the new things.
A couple of scriptures help apply these ideas:
54 And your minds in times past have been darkened because of unbelief, and because you have treated lightly the things you have received—
(Doctrine and Covenants 84:54)
