" Historical consciousness therefore leaves you, as does maturity itself, with a simultaneous sense of your own significance and insignificance. Like Friedrich's wanderer, you dominate a landscape even as you're diminished by it. You're suspended between sensibilities that are at odds with one another, but it's precisely within that suspension that your own identity--whether as a person or a historian--tends to reside. Self-doubt must always precede self-confidence. It should never, however, cease to accompany, challenge, and by these means discipline self-confidence. "
