The idea of home is bigger than the floorplan of any given four walls or the mass of any roof line. It cannot be compassed by rote recitations of suburb or postcode, nation or state. In last week's lecture, I mentioned the various definitions that dictionaries give for that small, heavily laden word, home. Tonight I would like to explore some of them: home as 'a place of origin, a native habitat', home as 'an environment offering security and happiness' and home as 'the place where something is discovered, founded, developed or promoted. A source.'
