What exactly is 'perishable' in The Perishable Empire? In his speech on the 'Government of India' in 1833, Thomas Macaulay pointed out that the only imperishable aspects of the British Empire are the arts, morals, literature and laws of England. Everything else is perishable. In the brief extract from Macaulay's speech that serves as an epigraph to this delightful volume, the only thing that is not mentioned, ironically, is the English language.
