    “I'm afraid that the following syllogism may be used by some in the future.

    Turing believes machines think
    Turing lies with men
    Therefore machines do not think

    Yours in distress,

    Alan”

    “I believe that at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted.”

    “The original question, 'Can machines think?' I believe to be too meaningless to deserve discussion.”

    “Those who can imagine anything, can create the impossible.”

    “I am not very impressed with theological arguments whatever they may be used to support. Such arguments have often been found unsatisfactory in the past. In the time of Galileo it was argued that the texts, 'And the sun stood still... and hasted not to go down about a whole day' (Joshua x. 13) and 'He laid the foundations of the earth, that it should not move at any time' (Psalm cv. 5) were an adequate refutation of the Copernican theory.”

    “It seems probable that once the machine thinking method had started, it would not take long to outstrip our feeble powers… They would be able to converse with each other to sharpen their wits. At some stage therefore, we should have to expect the machines to take control.”

    “A very large part of space-time must be investigated, if reliable results are to be obtained.”
    Alan Turing

    “The isolated man does not develop any intellectual power. It is necessary for him to be immersed in an environment of other men, whose techniques he absorbs during the first twenty years of his life. He may then perhaps do a little research of his own and make a very few discoveries which are passed on to other men. From this point of view the search for new techniques must be regarded as carried out by the human community as a whole, rather than by individuals.”

    “Finding such a person makes everyone else appear so ordinary…and if anything happens to him, you’ve got nothing left but to return to the ordinary world, and a kind of isolation that never existed before.”
    Alan Turing

    “I've now got myself into the kind of trouble that I have always considered to be quite a possibility for me, though I have usually rated it at about 10:1 against. I shall shortly be pleading guilty to a charge of sexual offences with a young man. The story of how it all came to be found out is a long and fascinating one, which I shall have to make into a short story one day, but haven't the time to tell you now. No doubt I shall emerge from it all a different man, but quite who I've not found out.”

    Alan M. Turing
    “Let us return for a moment to Lady Lovelace’s objection, which stated that the machine can only do what we tell it to do. One could say that a man can “inject” an idea into the machine, and that it will respond to a certain extent and then drop into quiescence, like a piano string struck by a hammer. Another simile would be an atomic pile of less than critical size: an injected idea is to correspond to a neutron entering the pile from without. Each such neutron will cause a certain disturbance which eventually dies away. If, however, the size of the pile is sufficiently increased, the disturbance caused by such an incoming neutron will very likely go on and on increasing until the whole pile is destroyed. Is there
    a corresponding phenomenon for minds, and is there one for machines? There does seem to be one for the human mind. The majority of them seem to be “sub-critical,” i.e. to correspond in this analogy to piles
    of sub-critical size. An idea presented to such a mind will on average give rise to less than one idea in reply. A smallish proportion are supercritical. An idea presented to such a mind may give rise to a whole “theory” consisting of secondary, tertiary and more remote ideas. Animals’ minds seem to be very definitely sub-critical. Adhering to this analogy we ask, “Can a machine be made to be super-critical?”

    “The popular view that scientists proceed inexorably from well-established fact to well-established fact, never being influenced by any unproved conjecture, is quite mistaken. Provided it is made clear which are proved facts and which are conjectures, no harm can result. Conjectures are of great importance since they suggest useful lines of research.”

    “[...] Ritardo ce ne sarà per forza, a causa di intoppi praticamente inevitabili, perché fino a un certo punto è meglio lasciare che ci siano intoppi piuttosto che spendere tempo sul progetto per essere sicuri che non ce ne siano (chissà quanti anni occorrerebbero per questa strada).”

    “Potremmo anche immaginare una macchina calcolatrice che viene fatta lavorare con una memoria basata sui libri. Non sarebbe molto facile, ma immensamente preferibile a un singolo lungo nastro. Per pura ipotesi supponiamo che le difficoltà implicite nell'uso di libri come memoria siano superate, cioè che si riesca a sviluppare gli artifici meccanici necessari per trovare il libro giusto, aprirlo alla pagina giusta e così via, imitando l'azione delle mani e degli occhi umani. Non si può girare una pagina molto velocemente senza strapparla, e se gli spostamenti dovessero essere numerosi e veloci, l'energia richiesta sarebbe molto grande. Se muovessimo un libro ogni millisecondo e ciascuno fosse mosso di dieci metri e pesasse 200 grammi, e se ogni volta l'energia cinetica fosse dispersa senza recupero, dovremmo consumare 10^10 watt, pari a circa la metà del consumo di energia della nazione. Per avere una macchina davvero veloce, allora, dobbiamo tenere la nostra informazione, o almeno una parte di questa, in una forma più accessibile di quella che può essere ottenuta con i libri. Sembra che questo risultato possa essere ottenuto solo al prezzo di sacrificare compattezza d economia, cioè tagliando le pagine dal libro e presentando ciascuna a un meccanismo di lettura separato. Alcuni dei metodi di memorizzazione che sono sviluppati ai giorni nostri non si allontanano molto da questo modello.”
