A mosque is proposed to be built near the World Trade Centre. It would be much better if the religious centre near the World Trade Centre is for all mainstream religions to share – as happens now on some university campuses, e.g. Monash, at Melbourne, Australia. It also has the advantage that people of one religion can occasionally meet the people of another, and they can all join in matters of public life that they all share. One religion only or religions in separate buildings shows we have learned no lessons from the disaster.
