雙語暢銷書《艾倫圖靈傳》第7章:運轉起來(57)
To understand the Turing model of 'the brain', it was crucial to see that it regarded physics and chemistry, including all the arguments about quantum mechanics to which Eddington had appealed, as essentially irrelevant.
In his view, the physics and chemistry were relevant only in as much as they sustained the medium for the embodiment of discrete 'states', 'reading' and 'writing'.
在他的觀點中，物理和化學唯一的用處，就是作爲離散狀態和輸入輸出的表現載體。Only the logical pattern of these 'states' could really matter.
真正重要的是這些狀態的邏輯模式。
The claim was that whatever a brain did, it did by virtue of its structure as a logical system, and not because it was inside a person's head, or because it was a spongy tissue made up of a particular kind of biological cell formation.
無論大腦要做什麼，都是因爲它的邏輯結構，而不是因爲它在人頭裏，也不是因爲它是由細胞組成的有彈性的組織。And if this were so, then its logical structure could just as well be represented in some other medium, embodied by some other physical machinery.
既然是這樣，那麼它的邏輯結構就可以用其它載體來實現，比如一臺機器。It was a materialist view of mind, but one that did not confuse logical patterns and relations with physical substances and thing, as so often people did.
這是唯物論的看法，它不會將邏輯模式與物理實體混淆，人們經常會把這搞混。In particular it was a different claim from that of behaviourist psychology, which spoke of reducing psychology to physics.
特別的是，這與行爲主義心理學的觀點不同，行爲主義者討論的是，把心理學歸約到物理學。The Turing model did not seek to explain one kind of phenomenon, that of mind, in terms of another. It did not expect to 'reduce' psychology to anything.
而圖靈機模型顯然不是要用其它東西來解釋思維現象，它並不是要歸約心理學。The thesis was that 'mind' or psychology could properly be described in terms of Turing machines because they both lay on the same level of description of the world, that of discrete logical systems.
他的觀點是，思維或者心理，之所以能用圖靈機來合理描述，是因爲在一個離散邏輯系統的世界的描述中，它們是處於同一層面的。It was not a reduction, but an attempt at transference, when he imagined embodying such systems in an artificial 'brain'.
這不是一種歸約，而是嘗試一種變換，他想象將這樣的系統，實現在一個人工的大腦中。
