“There are those who wish to read everything. Don’t vie with them. Leave well enough alone. It is nothing to you whether you read all the books there are or not. The number of books is infinite: don’t pursue infinity! Where no end is in sight, there can be no rest. Where there is no rest, there is no peace. Where there is no peace, God cannnot dwell. ‘His place,’ says the Prophet, ‘is in peace, and his abode in Sion.’” (Translated from the Latin by Jerome Taylor)
