Free from Lice

This was done partly by the invention of new words, but chiefly by eliminating undesirable words and by stripping such words as remained of unorthodox meanings, and so far as possible of all secondary meanings whatever. To give a single example. The word free still existed in Newspeak, but it could only be used in such statements as ‘This dog is free from lice’ or ‘This field is free from weeds’. It could not be used in its old sense of ‘politically free’ or ‘intellectually free’ since political and intellectual freedom no longer existed even as concepts, and were therefore of necessity nameless.
