Computers can do many things, but can they think? <strong>The</strong> idea <strong>of</strong> creating<br />

a machine that thinks goes back to the 17 th century, with the invention<br />

<strong>of</strong> mechanical calculators. If machines can mirror our logical<br />

processes, aren’t they thinking? With the move to electronic computers,<br />

we have been able to model neural structure and create increasingly more<br />

complex algorithms that can beat our best minds at strategic games, such as<br />

What would it mean to have a computer that became sentient, that had an<br />

internal life and feelings? Would such a machine become human?<br />

contemporary mind with computers, but it pre-dates electronic<br />

computing. Possibly the most important name associated with AI is<br />

the British mathematician Alan Turing.<br />

<br />

At the beginning <strong>of</strong> his career, Turing was fascinated by Kurt<br />

Gödel’s incompleteness theorem.<br />

Gödel opposed the logical approach <strong>of</strong> British philosopher<br />

Bertrand Russell, who contended that a mathematical<br />

statement is true if it could be proved. But pro<strong>of</strong> must occur<br />

within a system; thus, Russell and his former teacher Alfred<br />

North Whitehead created what they believed to be the logical<br />

foundations on which mathematics could be completely<br />

constructed. Gödel showed that Russell’s project failed.<br />

<br />

Gödel determined a method for mapping true sentences about<br />

mathematics onto true equations and false sentences about<br />

mathematics onto false equations. He then asked what would<br />

happen with the sentence “This sentence is not provable.” If it<br />
