I am a professor emeritus of economics. I have published around six dozen refereed scholarly papers in a variety of areas in economics, finance, mathematics, statistics, and cryptology, and I've had a life-long interest in the field of linguistics. I limit my Wikipedia editing primarily to these fields.

"Imagine there's no countries, it isn't hard to do. Nothing to kill or die for, and no religion too. Imagine all the people, living life in peace... You may say I'm a dreamer, but I'm not the only one. I hope someday you'll join us, and the world will be as one."

John Lennon

My credo[edit]

Morality

The Golden Rule: Do unto others as you would have them do unto you.

Corollaries:
  • Always consult your conscience.
  • Always act with integrity.
  • Be compassionate toward those who are suffering.
  • Show love: hope for good to come to all.
  • Purge bad conscience: Determine not to repeat past violations of the Golden Rule.
  • Use kindness to create good conscience: Do positive things for others.


Reality

Rational empiricism (the Scientific Method): Discern reality by applying logical inference to empirical observation.

Corollaries:
  • Reject supernaturalism and theism.
  • Always ask “How do we know that?” ; demand rigorous evidence.

Enlightenment

Cosmopolitanism: Be open to consideration of ideas from a wide variety of sources.

Corollary:
  • Engage in learning for life.

Bliss

Aestheticism: Continuously engage in the appreciation of beauty, and strive to create beauty.

Corollary:
  • See the beauty in everything, at every moment.

Striving-and-Serenity Balance: Find the best balance between serenity and striving to accomplish goals.

Corollaries:
  • Strive to improve the improvable.
  • In striving to accomplish, focus both on enjoying the process and achieving the goal.
  • Feel the exhilaration of accomplishment.
  • Always savor the present moment.
  • Find the best balance between simplicity and complexity.
  • Always leave time for reflection.
  • In seeking serenity, unclutter your mind and unclutter your external existence.
  • Focus on what you have rather than on what you do not and cannot have.
  • Receive bad fortune with equanimity.
  • Always be patient.
  • Avoid unrealistic expectations.
