Dennett imagines genetic information passing through digital representation before contributing to a fictional child, asking how informational continuity relates to physical carriers and reproduction.

This thought experiment asks whether an informational lineage can persist when its physical carrier changes. Dennett imagines genetic information passing through a digital representation before contributing to a fictional offspring. The question concerns what is transmitted and how, rather than whether parenting choices determine a child's character.

Separate preservation of a pattern from preservation of every process associated with its usual carrier. A different route can retain selected information while changing other causal conditions. In practical analogies, specify the feature being preserved and the evidence for continuity; identical content does not imply identical physical history or complete functional equivalence.

When to use it

Use when learning about information and embodiment or assessing what a change of representation preserves in a technical system.

How it can help

Distinguish a preserved informational pattern from its material implementation and the other causal processes associated with that implementation.
