A rule says, “You must do it this way.” A principle says, “This works … and has through all remembered time.” The difference is crucial. Your work needn’t be modeled after the “well-made” play; rather, it must be well made within the principles that shape our art. Anxious, inexperienced writers obey rules. Rebellious, unschooled writers break rules. Artists master the form.

A rule is any guiding principle or creative criterion. It might exist within the artist, the genre, or the culture. Rules, by their nature, are limitations.

Principles are fundamental truths that serve as the foundations for behavior that gets you what you want out of life. They can be applied again and again in similar situations to help you achieve your goals.

A rule is a way of structuring awareness.

In the practical sense the word principle may be applied to any underlying cause of more or less correlated facts in any particular field of investigation. The word principles, as applied to organization, is used by us strictly in the latter meaning.

PRINCIPLE is likewise such a law for action, except that it has not the formal definite meaning, but is only the spirit and sense of law in order to leave the judgment more freedom of application when the diversity of the real world cannot be laid hold of under the definite form of a law.

Jesus didn't forgive his executioners on principle but because in some unimaginable way he was able to love them.
'Principle' is an even duller word than 'Religion'.

Principles and rules are intended to provide a thinking man with a frame of reference.

Principles are like lighthouses. They are natural laws that cannot be broken. As Cecil B. DeMille observed of the principles contained in his monumental movie, The Ten Commandments, “It is impossible for us to break the law. We can only break ourselves against the law.” While

The principles — consistency, reciprocation, social proof, authority, liking, and scarcity

Principles are the territory. Values are maps. When we value correct principles, we have truth — a knowledge of things as they are.

When people in authority want the rest of us to behave, it matters — first and foremost — how they behave. This is called the “principle
