In the new ape society much communication was done with sounds, especially through the use of language
Through the use of language, thought could be converted with unprecedented clarity into a form which could enter the mind of another ape. However, it is very important to note that this conversion of thought into sounds is only considered appropriate when used as communication with other apes. There are very few circumstances under which it is considered appropriate for one to pronounce the language in one's head out loud. This is refered to as "talking to one's self" and is often considered as a sign of insanity, the lowest social rank assignable.
Well, fuck it! We're in charge of ourselves.
