In the early decades of the Industrial Revolution, machines were conceived primarily as agents of thermodynamic conversion: coal was burned to generate steam, which was then translated into mechanical work. This thermodynamic model of technology, heavily influenced by the rise of steam engines, naturally mirrored the prevailing nineteenth-century physiological view of the human body as an engine requiring chemical fuel to perform physical labor. However, mid-twentieth-century developments in cybernetics fundamentally altered this paradigm. By focusing on feedback loops and self-regulating systems, early cyberneticians proposed that both organisms and machines are governed not merely by energy transfer, but by the transmission and processing of information. A thermostat or an autopilot system did not interest these theorists because of the power it drew, but because of how it responded to messages from its environment to maintain stability. Consequently, the boundary between the mechanical and the organic began to dissolve. The language of thermodynamics—force, work, efficiency—was largely supplanted in theoretical circles by the language of communication—noise, entropy, and control. In this new light, the defining characteristic of life was no longer its capacity to burn fuel, but its ability to resist decay by organizing and acting upon environmental signals.
Which of the following best expresses the main idea of the passage?
- The transition from thermodynamic to cybernetic frameworks fundamentally redefined both machines and organisms as systems governed by information rather than energy.Answer
- BThe evolution of scientific technology continuously transforms how societies define the boundaries between life and non-life.
- CNineteenth-century technological developments, such as the steam engine, led physiologists to compare human bodily functions to thermodynamic processes.
- DEarly cybernetics proved that organic systems do not rely on thermodynamic principles of energy transfer to sustain themselves.
