A case to look through

A multicellular organism

How do locally competent cells become parts of a competent larger whole?

A multicellular organism is striking because its cells do not merely coexist. Their activities become organized around outcomes at a scale larger than any individual cell.

Start with the puzzle

The parts have competencies of their own.

Cells sense their surroundings, regulate internal states, move, communicate, repair damage, and pursue local physiological needs.

Yet in a healthy organism these local competencies participate in larger-scale processes: maintaining tissues, building anatomy, healing wounds, and preserving the organism.

That raises an alignment question that is easy to miss if we look only at the parts: how does competence at one scale become competence at another?

Try looking at this case through

Look at the failure

Local competence can become larger-scale pathology.

A cell can remain perfectly capable of survival, growth, resource acquisition, and reproduction while becoming badly integrated with organism-scale constraints.

Cancer therefore makes the scale question unusually visible: competence and alignment are always competence and alignment relative to something.

Look again

At what scale is the system detecting error and trying to correct it?
