“It's dangerous, son." "What's dangerous?" "When a man goes outside his house to look for peace.”

“When you start to live outside yourself, it's all dangerous.”

“Man is a rope stretched between the animal and the Superman—a rope over an abyss. A dangerous crossing, a dangerous wayfaring, a dangerous looking-back, a dangerous trembling and halting.”

“When contemplated in its extreme, almost any power looks dangerous.”

“Knowledge from experience: the heart goes blind because the need is stronger than anything else. Your ego is blind, your id is eager. It will get to the point of smashing everything. When there is a danger from outside, you bolt, but when the danger comes from inside, how can you bolt? The danger from inside is that complicated thing, the love of the wolf, the complicity that attaches us to that which threatens us.”

“It is dangerous to lock oneself away and lose track of what is happening outside.”
