That is the new and excellent biography by Mark Eisner, here is one good bit:
“The antagonism toward Borges may exist in an intellectual or cultural form because of our different orientation,” Neruda answered. “One can fight peacefully. But I have other enemies — not writers. For me the enemy is imperialism, and my enemies are the capitalists and those who drop napalm on Vietnam. But Borges is not my enemy…He understands nothing of what’s going on in the contemporary world; he thinks that I understand nothing either. Therefore, we are in agreement.”
After [Juan Ramón] Jiménez’s “great bad poet remark, Neruda and his friends started to prank call Jiménez’s house, hanging up the phone as soon as he answered.
This book is remarkably well-constructed and easy to read, the best treatment of one of the 20th century’s greatest poets.
