“[Peace must be] founded on truth, built according to justice, vivified and integrated by charity, and put into practice in freedom.”

Speech to the Conservative Party Convention 1982 https://www.margaretthatcher.org/document/105032
First term as Prime Minister

Light (1919), Ch. XX The Cult
Context: There must be justice, not charity. Kindness is solitary. Compassion becomes one with him whom we pity; it allows us to fathom him, to understand him alone amongst the rest; but it blurs and befogs the laws of the whole. I must set off with a clear idea, like the beam of a lighthouse through the deformities and temptations of night.

The Mission Song (2006)

Nobel Address (1991)
Context: The new integrity of the world, in our view, can be built only on the principles of the freedom of choice and balance of interests. Every State, and now also a number of existing or emerging regional interstate groups, have their own interests. They are all equal and deserve respect.
We consider it dangerously outdated when suspicions are aroused by, for instance, improved Soviet-Chinese or Soviet-German, German-French, Soviet- US or US-Indian relations, etc. In our times, good relations benefit all. Any worsening of relations anywhere is a common loss.

Context: To live with integrity in an unjust society we must work for justice. To walk with integrity through a landscape strewn with beer cans, we must stop and pick them up.

1930s, Quarantine Speech (1937)
Context: Those who cherish their freedom and recognize and respect the equal right of their neighbors to be free and live in peace must work together for the triumph of law and moral principles in order that peace, justice, and confidence may prevail in the world. There must be a return to a belief in the pledged word, in the value of a signed treaty. There must be recognition of the fact that national morality is as vital as private morality.
