“For reasons that are not well understood, war's codes are safer for most of us than love's.”

“Safer than we are.” I told Franny. “Safer than love.” “let me tell ya kid,” Franny said to me, squeezing my hand. “Everything’s safer than love.”

“Safer to be feared than loved.”

“It is safer to be feared than loved”

“You gotta admit, it's a messed-up world when going to war is safer than staying home.”

“Immutable objects are simple. They can only be in one state, which is carefully controlled by the constructor. One of the most difficult elements of program design is reasoning about the possible states of complex objects. Reasoning about the state of immutable objects, on the other hand, is trivial. Immutable objects are also safer. Passing a mutable object to untrusted code, or otherwise publishing it where untrusted code could find it, is dangerous — the untrusted code might modify its state, or, worse, retain a reference to it and modify its state later from another thread. On the other hand, immutable objects cannot be subverted in this manner by malicious or buggy code, so they are safe to share and publish freely without the need to make defensive copies.”
