The Duff Cooper Prize was going through a dry patch at the end of the 1960s. This erudite work would be of interest to students of English criticism tracing the history of critical thought from Thomas Carlyle onwards. For others it is probably a bit too obscure.
The author had clearly read and pondered a great many authors, a few of whom I had heard of, many being literary critics or early English professors whose names one may have come across, but whose works lie mouldering.
It's also deceptively long. Dense type, not one you can skim. It does get a bit easier as you go through but require perseverance.
In conclusion the author wonders whether a general education and life experience counts for rather more than narrow university English curricula. In that he is probably right. Don't confuse having had an education with being educated, or knowing material for examinations with being wise.
