Liberalism opens cultural space for pluralism to fill.

Liberalism must never be allowed to become annihilation of all that might fill that open space.

If this latter happens — if all particular beliefs are corroded and eaten away by fanatical skepticism or battered with dogmatic anti-dogmatism — not only does liberalism become nihilistic — it becomes a nihilistic monism, antipluralism, illiberalism — a negation of itself into a something worse than anything it negates.

(So says an exnihilist, who wishes to tap the nothingness, and allow epiphanic somethingness to pour in.)
