At school, if another child encouraged me to do something stupid, doubtless a teacher would upbraid me by saying something like, "Well, if Charlie told you to put your hand in the fire would you do it?" Of course, one was supposed to be chastened: no, certainly one wouldn't place one's hand in a fire on Charlie's behest. And, yes, I'll admit, what I've just done was probably almost as stupid: I'll consider myself rebuked. Sorry, Miss.
As I've got older, however, there are one or two people whose judgement I trust so implicitly that, yes, if they told me to put my hand in the fire, I just might.
So, if Gabriel Josipovici says something is good, it is. Full stop. Here he is blurbing RSB's Book of the Month, Peter Hawkins' Dante: A Brief History:
Peter Hawkins' knowledge of and passion for Dante shines through every page of this elegantly written book. He writes, moreover, with passion and precision. This is not only a superb introduction to Dante, but a work which will move and enlighten those thoroughly steeped in a poet who remains, seven centuries after his death, still very much our contemporary.
