Wiener was wrong. There is ***no*** #communication ***in*** either the animal or in the machine, only #control by the application of #constraints to their inner flow of matter and energy.

Communication is established ***between*** animals and/or machines, and, as Shannon correctly recognized, requires an independent communication #channel susceptible to the environmental disturbance called #noise.

In order to be able to communicate animals and machines must share a common #language or cipher #rules used to code their respective messages. Communication is always one-way and does not require feedback. The sender has no control over the message after it is sent through the channel.

A special case of communication is #observation where the communication is established between the observer system and phenomena in its environment not necessarily produced by other systems "languaging".
