Sir Bernard Rowland Crick (16 December 1929 – 19 December 2008) was a British political theorist and democratic socialist whose views can be summarised as "politics is ethics done in public". He sought to arrive at a "politics of action", as opposed to a "politics of thought" or of ideology, and he held that "political power is power in the subjunctive mood." He was a leading critic of behaviouralism.
Crick is today popularly remembered for having written the first version of the controversial Life in the UK test, a requirement to obtain British citizenship but criticised since its inception for its factual errors and misrepresentations.
