From Julian Higman, Wantage, Oxfordshire, UK
In a way, the question “When did time begin?” is a non-question. Time is our manufactured, mental measuring stick, expressed as a word, to gauge and so compare motion. In this sense, it will have begun sometime after we started to use speech, between two other questions you posed: “When did Homo sapiens originate?” and “When did civilisation arise(22 February, p 31)?”
