In George Orwell's book, "Why I Write" he listed 4 reasons that people write. Below is his 4th reason. (The other 3 are in the previous post if you have not seem them)
POLITICAL PURPOSE. This, in part, is "the desire to push the world in a certain direction, to alter people's idea of the kind of society that they should strive after".
Orwell also said that all writing was political. This helps but doesn't give us insight into the person's motives? What is driving the push? Do we want to help or hurt? If we want to help what motives are best?
The thread that may reveal the motives is likely found in the over all values a person refects in their life. An example of good values could become a yardstick. Does the person life reflect being:
"Trustworthy, Loyal, Helpful, Friendly, Courteous, Kind, Obedient, Cheerful, Thrifty, Brave, Clean, and Reverent".
For many of us these words are recognizable as the "Boy Scouts Law". They may seem simple but they work fine as standards. Each one can be a value for why we would write.
Recognize that what is written is being driven by a motive and try to learn how to identify whether it is good or bad.
