About this quote
Technical control over matter can be easier than moral transformation of human beings and institutions. The contrast turns nuclear science into a warning that destructive motives cannot be engineered away.
When to use it
- A weapons laboratory pairs technical safeguards with independent ethical and political oversight.
- A peace program addresses fear and propaganda instead of assuming new machinery will change hostility.
- A company treats harmful incentives as a cultural problem rather than expecting one security tool to solve them.
