Why Physics Needs Philosophy by Tim Maudlin.
Philosophers strive for conceptual clarity. Their training instills certain habits of thought—sensitivity to ambiguity, precision of expression, attention to theoretical detail—that are essential for understanding what a mathematical formalism might suggest about the actual world. Philosophers also learn to spot the gaps and elisions in everyday arguments. These gaps provide entry points for conceptual wedges: nooks where overlooked alternatives can take root and grow.
