The ice is near, the solitude is immense, but how peacefully everything lies in the light! How freely one breathes! How much one feels within oneself! This is what the philosopher Friedrich Nietzsche calls to us, conveying a strangely powerful image of contrasts, but at the same time raising a multitude of questions: Can solitude be understood positively? Is there something liberating inherent in being alone, alongside all the painful aspects? Does the contrast between solitude and simultaneous freedom reveal a special feeling of sublimity? Friedrich Nietzsche has perhaps illuminated solitude as a fundamental condition of humanity in all its subtle variations and facets like no other philosopher before him. His contemplation of solitude is a constant oscillation between life and philosophy, between deep pain and soaring joy.
