For my sister, Alex, who will start her Economics major this July
Economists are philosophers of human action.
They’re close to psychologists, neurologists, sociologists, anthropologists, and ethicists.
But psychologists focus on the mind behind the human action, neurologists focus on the underlying brain, sociologists on the surrounding society, anthropologists on the enveloping culture. Ethicists focus on the aesthetics of human action, on what human action should be.
Economists, on the other hand, focus on the actions themselves, on trying to understand them in their own terms. They ask questions like:
What patterns does human action follow? What different kinds can we usefully distinguish? Why are these actions taken? What are the goals behind these actions? What would the consequences be of these actions? Why do these actions have these consequences? In other words, what is the interplay between goals, conditions, actions, and consequences? If someone took these actions what actions are others expected to take? How will these actions affect others? What are the best actions to take given these goals? How best to organize and coordinate human action? What are the limits of human action? How to improve human action?
Free trade is when a trade doesn’t need the consent of anyone but the traders.
A trader is an owner of property to be traded.
The above definitions after this inspiring but somewhat muddled definition of free trade. I particularly like the second, satellite definition because it safeguards the first: If you want to contort a party into a trade and still call it free, having to specify exactly what it is this party owns can make the contortion clearer—all sorts of patronizing, noble-sounding words can be used to camouflage deception, but to own is a very strong word that makes us pay attention and rightly so.
It’s claimed that government is a legitimate party in sex trade (say, prostitution) because it has to defend public morals, clients and prostitutes, but what is it that gov’t owns? Clients’ and prostitutes’ bodies and money? Public morals? Gov’t is also claimed a legitimate party to international trade (say, immigration) in the name of protecting domestic industry, but what is it that gov’t owns? Domestic industry? Employers’ or employees’ time and money?
Sarah Manguso wrote a short memoir on her 9 years with a strange, terrible, Guillain Barre -ish disease: The Two Kinds of Decay. There’s something about her style—short paragraphs, understatement, detachment—that compels me, and though on occasion she can be clumsy with metaphors, she can write fragments of simple, unexpected poignancy:
I waited seven years to forget just enough—so that when I tried to remember, I could do it thoroughly. There are only a few things to remember now, and the lost things are absolutely, comfortingly gone.
Game: 2 players take turns to say a number between 1 and 9. Numbers may not be repeated. The goal is to be the first to say 3 numbers which add up to 15.
Sounds like fun? Try it with a friend!
Fun it ain’t.
It’s hard to remember the said numbers and “playing” is a chore involving many additions in your head. Maybe it’s fun for the better short-term memory endowed or those who enjoy arithmetic but that ain’t me.
Turns out that game above is none other than the beloved tic-tac-toe. You see:
This is what I love about information design (and what I tried to do in my calendars) this is its art, its magic: it can turn a chore into a game! It recasts our weaknesses —linear, verbal processing— into a form suitable for our talents —gestalt visual processing.
In math words: it finds useful language-graph same-shapes (isomorphisms)!
