“Society already possesses the psychological techniques needed to obtain universal observance of a code -- a code which would guarantee the success of a community or state. The difficulty is that these techniques are in the hands of the wrong people--or, rather, there aren't any right people.”

“I would rather have ideas and some difficulties of technique than a perfect technique and no ideas.”

“The essence of successful discipline is not technique; rather, it is self-confidence.”

“Moral codes are like the ocean. Some people live by them, while others, such as myself, would rather live by a lake.”

“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.”

“Man cannot be enlightened through any organization, creed, dogma, priest or ritual, nor through any philosophical knowledge or psychological technique. He has to find it through understanding the contents of his own mind, through observation, not through intellectual analysis or introspective dissection.”
