The volume that you show was published by Thomas Newcomb for Andrew Crook (publisher - https://en.wikipedia.org/wiki/Andrew_Crooke_and_William_Cooke) at the Green-Dragon in St Paul’s Churchyard in 1666. It is dedicated to Charles II and the dedication - an epistle - contains reference to the recent English Civil War (1642–1651). This epistle is signed “Joh Exon.” (Bishop of Exeter – John Gauden (1605 – 23 May 1662)
In the Section “To the Reader” the editor (Andrew Crook) states that he has amended and corrected some of the text of “The Life of Richard Hooker.” The volume then continues with the works of Richard Hooker (25 March, 1554 – 3 November 1600).
Richard Hooker’s works have been more or less in print since he wrote them but the English in many of the editions has been updated as language changes and spelling became more regular.
It is therefore not the original, and although it provides a possible early use of “human being” it cannot be dated with absolute certainty to 1590 - however, this use still predates the OED’s 1694.
