Andrew D. Irvine says that PM sparked interest in symbolic logic and advanced the subject by popularizing it; it showcased the powers and capacities of symbolic logic; and it showed how advances in philosophy of mathematics and symbolic logic could go hand-in-hand with tremendous fruitfulness.[1] PM was in part brought about by an interest in logicism, the view on which all mathematical truths are logical truths. Though flawed, PM would be influential in several later advances in meta-logic, including Gödel's incompleteness theorems.[2] The logical notation in PM was not widely adopted, possibly because its foundations are often considered a form of Zermelo–Fraenkel set theory.[citation needed]
