Multiple Realizability｜多重實現：同一種心智功能若能由不同物理系統實現，就不必綁死單一腦狀態

The multiple realizability thesis holds that the same higher-level or mental kind may be realized by different lower-level physical states or systems. It has been important in debates over whether psychological kinds can be straightforwardly identified with single neural kinds.

多重實現到底有多普遍，以及它是否真的阻止 reduction，都有大量哲學與科學爭論；不是任何表面相似功能都算同一 kind。
