Tom Lockhart focuses on the history of early analytic philosophy, especially the work of Frege. Much of his work concerns the relationship between language, logic, and world which is presupposed by Frege's claim that numbers are objects. He also works on the way in which Frege inherits and transforms Kant's claims in the philosophy of mathematics and logic, and the manner in which Frege's work is inherited and transformed by early and late twentieth-century philosophers of mathematics and language. Recently, he's been working on so-called "disjunctivist" arguments in the philosophy of perception.
On the other hand, he explores whether one could deploy disjunctivist forms of argument in other areas of philosophy: for example, in the philosophy of action and the philosophy of language.
