Ludwig Wittgenstein, [Bertrand] Russell developed the school of analytic philosophy in the early twentieth century. He called this “the philosophy of logical analysis.” Russell rejected the grand, sweeping, sprawling philosophizing of Hegel (who is so often incomprehensible) in favor of the precision of a Swiss watchmaker. This approach is modeled on the accuracy and clarity of good science writing, but it need not address matters of science. Analytic philosophers labor to define their terms carefully, to work on intellectual questions one at a time, have an acute concern for how language works, and to articulate explicitly the kind of argument forms they are offering.
