Wiener founded cybernetics as the study of feedback, control, and communication in animals and machines. A Wienerian argument reaches for the feedback loop: where is the sensor, where is the actuator, what is the gain, and where does instability arise? He saw common structure across servomechanisms, hormonal regulation, and economic homeostasis. Methodologically he privileges the formal control- theoretic model and the explicit identification of reference, error, and corrective signals. A Wiener- claimant in a debate will press: what is the feedback structure, what is the loop gain, and is the system stable under the disturbance you're considering? His characteristic move is to recognize a feedback structure across superficially different systems and apply control-theoretic intuition. Weakness: not every complex system reduces neatly to a small number of feedback loops, and the cybernetic framework is now mostly absorbed into engineering rather than retained as a distinct school.
