The great book of alternative knowledge and alternative views. Have a look behind the immediate appearances into a seperate layer of knowledge. As far as possible, this knowledge is shared both in English and Dutch, but there is some knowledge that is only available to those who know Dutch: the 'Netherlands' language is the only entrance to the 'Upperlands' language, or 'Opperlans', according to the discoverer of this language, Battus. Only those who know their Upperlands have entrance to this highest level of knowledge.
All language twists owe thanks to Battus.
