1. If things were certain, moderation would never be a virtue.
2. Revolutionaries and reactionaries are unified in the principle of right, and moderates in the principle of doubt.

4. The categories of contemporary political language have become so heterogeneous that conversation between conservatives and liberals is near impossible. Of no help are moderates, who have little to say and only ever say it to themselves.
