The Crisis of Scientific Paradigms: The Temporal Paradox of Heat Death and Evolution

Since the second half of the 19th century, science and technology have entered a new era of comprehensive development.Under this context, classical scientific paradigms have become fragmented along the fundamental dimension of 'time.' The core of this crisis lies in: Why do all things simultaneously 'deteriorate' and 'evolve' in a world governed by physical laws?

Cognitive Conflict Between Two Temporal Frameworks

  • Limitations of Mechanistic Determinism: The laws of motion in classical mechanics are reversible and symmetric under time reversal. This means that in Newton's world, time is merely a parameter without true 'historicity.' However,statistical physics played a crucial role in the revolution of Newtonian mechanics, revealing the irreversibility of macroscopic processes.
  • Entropy Increase and Heat Death: When the second law of thermodynamics was formulated, it already confronted the issue of irreversibility in natural processes. The law describes the directionality of energy transfer: an isolated system always evolves toward uniformity, simplicity, and the elimination of differences, ultimately reaching an irreversible state of 'stillness' where no physical distinctions remain.
  • The Evolutionary Nature of Evolution: In stark contrast to physics' 'deterioration theory,'biological development provides another temporal arrow โ€” the arrow of evolution. Complex living organisms continuously evolve from lower to higher forms and from simple to complex structures, demonstrating the miracle of systems spontaneously generating ordered structures.
Thought Experiment: A Sealed Glass Bottle
Imagine a sealed bottle: if it were purely a physical system, it would evolve toward a state of uniform molecular distribution (heat death); but if life exists within it, it would use energy to build complex structures (evolution). Physics claims the world is 'decaying,' while biology claims it is 'progressing.' This cognitive rift foreshadows the emergence of a systemic holistic perspective.
