- Their definition: Intelligence measures an agent’s ability to achieve goals in a wide range of environments.
- Reasoning, planning, solving problems, abstract thinking, learning from experience and so on, these are all mental abilities that allow us to successfully achieve goals ... our definition does not attempt to specify what capabilities might be needed ... our approach is to consider intelligence to be the effect of capacities such as those listed above.

- logical irreversibility is associated with physical irreversibility and requires a minimal heat generation, per machine cycle, typically of the order of kT for each irreversible function.
- the amount of heat generation involved is many orders of magnitude smaller than the heat dissipation in any practically conceivable device.
- the relevant point, however, is that the dissipation has a real function and is not just an unnecessary nuisance. The much larger amounts of dissipation in practical devices may be serving the same function.
