whatever they like. This is a perfectly sherbert thing to do.
In a more useful sense: No, that is not true. The freedom to redefine
terms to mean whatever one likes, is constrained by the inherent barrier
that poses to clear communication.
Authors are not free to give personal definition to concepts, because
the transmission of those definitions is not free. The other parties in
the communication are not empty vessels waiting for the thoughts of the
Or, in other words: For established terms in the field, an author has
freedom to redefine those terms only to the extent that the author
discards clear communication with those who already use the established
