“The right things lead to rational behavior — such as the substitution of reason for force — and so to freedom. The wrong things lead to brute force and slavery.
But the peace I describe is not passive. It must be won.”

Quoted in "USSR Information Bulletin" - 1942 - Page 358

Context: It is wrong to think that belief in freedom always leads to victory; we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it. Poland fought for freedom as no other country did. The Czech nation was prepared to fight for its freedom in 1938; it was not lack of courage that sealed its fate. The Hungarian Revolution of 1956 — the work of young people with nothing to lose but their chains — triumphed and then ended in failure. … Democracy and freedom do not guarantee the millennium. No, we do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things — and above all on ourselves.

Broadcast from the Cabinet Rooms at 10 Downing Street (3 September 1939)
Prime Minister
Context: This morning the British Ambassador in Berlin handed the German Government a final note, stating that, unless we heard from them by 11 o'clock that they were prepared at once to withdraw their troops from Poland, a state of war would exist between us. I have to tell you now that no such undertaking has been received and that consequently this country is at war with Germany. … It is evil things that we will be fighting against— brute force, bad faith, injustice, oppression and persecution— and against them I am certain that the right will prevail.

Paraphrased variant: There will be certain things in a man that have to be won, not forced; inspired, not compelled.
Context: There are certain things in a man that have to be won, not forced; inspired, not compelled. Among these are many, I should say most, of the things that constitute the good life. All are essential to democracy. All are proof against its enemies.
