Cosmopolitanism

Political borders may not mark the limits of what people owe one another.

01 / PLAINLY

What it means, plainly

Cosmopolitanism gives moral or political importance to every person beyond citizenship or nation.

02 / CONTEXT

A little more

Cosmopolitanism gives moral or political importance to all persons beyond citizenship and nation. Moral, legal, cultural, and institutional versions carry different commitments.

03 / WHY IT MATTERS

Why it matters

It broadens the map of affected people when a decision crosses borders, as climate policies often do.

04 / EXAMPLE

A familiar example

A climate policy may be judged by current voters and by people abroad who will bear its effects.

05 / LIMIT

What it does not mean

It does not necessarily require a world state or the abandonment of local and national attachments.

06 / NOTICE

Notice it in your day

Choose a policy with international effects and map who gains or loses inside and outside the country. Ask whether the border marks a moral difference or only an institutional one.

FINAL NOTE

The idea worth keeping

Check whether a border explains a moral difference or merely marks an institution's reach.
