‘Turing Believes Machines Think’ is a setting of British computer pioneer Alan Turing’s tragic last syllogism:

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

Yours in distress, Alan

This curious text appears at the end of a letter from Turing to a friend, conveying his distress at his prosecution for a relationship with a man. I’ve tried to express Turing’s fear that his life’s work – that of making ‘machines think’ – will be nullified by his criminal conviction.

The work was commissioned and premiered by the Sydney Gay and Lesbian Choir.
