Signature Books has posted an excerpt from Frances Lee Menlove's book 'The Challenge of Honesty'. The relevant portion of the link is Chapter 4: If Not Now, When? Mormon Women and the Priesthood.
It is an excellent essay, thoroughly researched, and makes a spectacular and coherent argument for why women should be ordained to the Priesthood (or rather, re-ordained).
You can find the excerpt here for your reading enjoyment. Take some time to treat yourself to one of the great LDS writers, and to soak up some knowledge on this important cause.
