Philosophy has become an increasingly academic discipline. More of its practitioners lament this situation than occurs with the sciences; nonetheless most new philosophical work appears in academic journals. Major philosophers through history—Plato, Aristotle, Socrates, Augustine, Descartes, Kierkegaard, Nietzsche—have become as canonical as any writers. Some recent philosophy works are argued to merit the title "literature", but much of it does not, and some areas, such as logic, have become extremely technical to a degree similar to that of mathematics.
