Madam, - With regard to the current discussions on embryo research, I am reminded of Martin Luther King's words during the civil rights campaign of the 1960s. "Cowardice asks the question, 'Is it safe'? Expediency asks the question 'Is it politic'? Vanity asks the question, 'Is it popular?' But conscience asks the question, 'Is it right?' " - Yours, etc.,
