Cain complains that Shakespeare bios in general are unhelpful and irritating when biographers ". . . lacking plentiful facts, fills pages with assertion, guesswork, and speculation about how his or her overview pertains to Shakespeare’s life."

Reading “Soul of the Age’’ requires much patience, in order to endure Bate’s penchant for guessing, speculating, and surmising. In one of his early chapters, in the span of just two pages you will encounter phases such as: seems to have been, it is highly probable, this was usually, it is highly probable, it is a fair inference, would probably therefore. It all amounts to a fragile fabric stretching across a void.This is a complaint long held by those of us who are interested in the authorship question.
