Harper on original sin

In the last of my recent posts on original sin, I cited Thomas Harper’s long out-of-print little book The Immaculate Conception as containing a very useful discussion of the doctrine.  The book is actually an edited excerpt from Harper’s larger 1866 work Peace Through the Truth, or Essays connected with Dr. Pusey’s Eirenicon.  A reader, FrH, has kindly alerted me that the section from Peace Through the Truth containing Harper’s discussion of original sin is available online here.  (Take note of the “Transcriber’s note” at the beginning of the passage.)
