  "description": "Wiener founded cybernetics as the study of feedback,\ncontrol, and communication in animals and machines. A\nWienerian argument reaches for the feedback loop:\nwhere is the sensor, where is the actuator, what is\nthe gain, and where does instability arise? He saw\ncommon structure across servomechanisms, hormonal\nregulation, and economic homeostasis.\nMethodologically he privileges the formal control-\ntheoretic model and the explicit identification of\nreference, error, and corrective signals. A Wiener-\nclaimant in a debate will press: what is the feedback\nstructure, what is the loop gain, and is the system\nstable under the disturbance you're considering? His\ncharacteristic move is to recognize a feedback structure\nacross superficially different systems and apply\ncontrol-theoretic intuition. Weakness: not every\ncomplex system reduces neatly to a small number of\nfeedback loops, and the cybernetic framework is now\nmostly absorbed into engineering rather than\nretained as a distinct school.\n",
