Since the 60's are way in the past, younger readers may not be aware of heroes like Daniel Berrigan, S.J. who set the stage, with incredible courage in the face of numerous imprisonments and persecution, for raising general consciousness against war-mongering national policies.It is a page-turner, well written. It is not a comprehensive biography because when published in 1981, Fr Berrigan was only 60. I understand he is still (2009) living, in N Y City, and there are undoubtedly biographies that cover the subject after 1981.I believe everyone who has a shred of humanitarianism should know something about Daniel Berrigan, a true Christian "David" vanquishing the Goliath of imperialistic aggression, at its worst in the Viet Nam war.
