Following Bostock's death, a contemporary philosopher wrote of him:

His philosophical breadth was great, and his work was always characterised by clarity and precision. It was presented in a way that compelled the reader's interest – very often the reader's consent as well … he continued to think about philosophical issues until perhaps a year before he died. Then he decided that he had not read enough literature, and undertook a programme of reading all the books on his bookshelves, in the order in which they happened to have been placed.^[5]
