“Anyone who maintains absolute standards of good and evil is dangerous. As dangerous as a maniac with a loaded revolver.”

“Danger manifests itself in many ways, Peter. Brilliance of mind can be as dangerous as a loaded weapon.”

“In this world, there is no absolute good, no absolute evil," the man said. "Good and evil are not fixed, stable entities, but are continually trading places. A good may be transformed into an evil in the next second. And vice versa. Such was the way of the world that Dostoevsky depicted in The Brothers Karamazov. The most important thing is to maintain the balance between the constantly moving good and evil. If you lean too much in either direction, it becomes difficult to maintain actual morals. Indeed, balance itself is the good.”

“Anyone who is disturbed by the idea of newts in a nightclub is potentially dangerous.”

“Dangerous thing, giving humanity the knowledge of good and evil. And the capacity to make the wrong choice more often than not.”

“The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.”
