Humans are the only species that cooperates on a large scale with their dead

Yes: no other species transmits accumulated knowledge across generations or gives up present consumption for individuals who will be born two centuries from now. That shared inheritance is the foundation of productivity.

Humans are the only species that cooperates on a large scale with their dead. Almost nothing we know was discovered by us: the language we speak, the Civil Code of **1804**, the bridge we cross every morning.

## A mediocre primate with a library

A human being in isolation is a mediocre primate with bad teeth. Connected to that inheritance, it is the most powerful thing biology has ever produced. Intelligence does not live in individual skulls: it lives in transmission, and we are terminals of a network with nodes buried centuries ago. Writing, some **5,000** years ago, allowed that network to stop depending on the memory of the living.

## Working for those not yet born

The reverse is also true. We plant trees whose shade we will never see and give up present consumption for hypothetical grandchildren. No other animal makes deliberate sacrifices for individuals who will exist **two hundred** years from now.

## The inheritance that sustains the present

That is an intergenerational transfer: public debt, pensions and public works paid for by those who come later. From there comes productivity: nobody reinvents the wheel before breakfast. What sets us apart is not intelligence or language, but the direction of our effort, aimed at the absent. This is not financial or legal advice.
