Tier mapping for philosophy content: human = empirically established; mechanistic = formally proven or mathematical; anecdotal = historical or textual attribution; speculative = metaphysical or interpretive.\n- Cite real sources only: primary works, papers, books, with exact quotes where verifiable. A claim with no source is marked unsourced.\n- State disconfirming edges plainly. A reductionist objection in the Weinberg style is content, not a threat.\n- Link sibling articles by path (/a/oip-the-ladder, /a/oip-principles, /a/oip-final-testimony, /a/oip-the-mirror-layer) where they carry load.\n\nNEVER:\n- Never overclaim. The synthesis is a lens; the actual words of the subject stay theirs.

The paper proposes that self-organizing systems at equilibrium with their environment minimize variational free energy.

Free energy minimization unifies perception, action, and learning under one imperative.\\n\\n## Key passages from the paper\\n\\nThe abstract states: \\\"A free-energy principle has been proposed recently that accounts for action, perception and learning. This Review looks at some key brain theories in the biological (for example, neural Darwinism) and physical (for example, information theory and optimal control theory) sciences from the free-energy perspective.\\\"\\n\\nOn motivation: \\\"The defining characteristic of biological systems is that they maintain their states and form in the face of a constantly changing environment... the probability of these... sensory states must have low entropy.\\\"\\n\\nOn the principle itself: \\\"The free-energy principle... says that any self-organizing system that is at equilibrium with its environment must minimize its free energy.\\\"\\n\\nOn surprise: \\\"Entropy is also the average self information or ‘surprise’ (more formally, it is the negative log-probability of an outcome).\\\"\\n\\nOn the bound: Free energy serves as an upper bound on surprise. Minimizing it enables approximate Bayesian inference via the recognition density.\\n\\n## Convergence patterns\\n\\nThe work bridges thermodynamics to neural processes.
