In sum, philosophy is not science. For it employs the rational tools of logical analysis and conceptual clarification in lieu of empirical measurement. And this approach, when carefully carried out, can yield knowledge at times more reliable and enduring than science, strictly speaking. For scientific measurement is in principle always subject to at least some degree of readjustment based on future observation. Yet sound philosophical argument achieves a measure of immortality.
So if we philosophers want to restore philosophy’s authority in the wider culture, we should not change its name but engage more often with issues of contemporary concern — not so much as scientists but as guardians of reason. This might encourage the wider population to think more critically, that is, to become more philosophical.
