If not now when?

[Tintin19]

Does anybody know the correct words to a short poem that starts with something like 'Without words there would be no speech ......' and ends with 'If not me then who, and if not now, when'?

I'm not sure about the opening words you quote, but the 'if not me then who' part would seem to be a quotation from Rabbi Hillel. For further information, click http://phrases.shu.ac.uk/bulletin_board/13/message
