In the twenty-first century, philosophy still needs to raise the question of the meaning of being. We therefore, follow Heidegger's return to Parmenides—for being is neither a being nor a concept; rather, it is an essentially ambiguous universal. Being's ambiguity allows us to understand both why it withdraws from thought and why there is something rather than nothing. The problem for philosophy then becomes: How can we think the original ambiguity of being without disambiguating it? Heidegger's answer—ironically or not—is by not thinking it.
