"Ask anyone committed to Marxist analysis how many angels on the head of a pin, and you will be asked in return to never mind the angels, tell me who controls the production of pins"

This quote by Joan Didion is a criticism of those who concentrate on abstract concepts rather than the practical truths of life. She is suggesting that those who are committed to Marxist analysis must be more concerned with the useful ramifications of their theories, such as who manages the production of pins, rather than disputing abstract concepts such as the number of angels can fit on the head of a pin. This quote is a suggestion that Marxist analysis must be used to understand and enhance the product conditions of individuals's lives, instead of getting lost in abstract arguments. It is a call to action for those who are dedicated to Marxist analysis to concentrate on the useful implications of their theories and to use them to enhance the lives of those who are oppressed and marginalized.
