SIR – Your Leading Article on the rights and wrongs of boiling lobsters alive (April 26) brought to mind a question asked of would-be university philosophy students back in the Seventies.

The answer? As the logician said at the time: work it out. Dr Christopher Ray Former High Master, The Manchester Grammar School Didsbury, Manchester
