Alan Turing

"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."

"We can only see a short distance ahead, but we can see plenty there that needs to be done."

"I want a permanent relationship, and I might feel inclined to reject anything which of its nature could not be permanent."

"Science is a differential equation. Religion is a boundary condition."

"The idea behind digital computers may be explained by saying that these machines are intended to carry out any operations which could be done by a human computer."

"I have had a dream indicating rather clearly that I am on the way to being hetero, though I don't accept it with much enthusiasm either awake or in the dreams."

"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."
