“To free one's mind of chains is to free it of the care of what is acceptable or viewed so by society, this is when true freedom is discovered.”

Source: Bandits (1969), Chapter Two
Context: Banditry is freedom, but in a peasant society few can be free. most are shackled by double chains of lordship and labour, one reinforcing the other. For what makes peasants the victim of authority is not as much their economic vulnerability - indeed they are as often as not virtually self sufficient - as their mobility.

1990s, Long Walk to Freedom (1995)
Context: It was during those long and lonely years that my hunger for the freedom of my own people became a hunger for the freedom of all people, white and black. I knew as well as I knew anything that the oppressor must be liberated just as surely as the oppressed. A man who takes away another man's freedom is a prisoner of hatred, he is locked behind the bars of prejudice and narrow-mindedness. I am not truly free if I am taking away someone else's freedom, just as surely as I am not free when my freedom is taken from me. The oppressed and the oppressor alike are robbed of their humanity.
When I walked out of prison, that was my mission, to liberate the oppressed and the oppressor both. Some say that has now been achieved. But I know that that is not the case. The truth is that we are not yet free; we have merely achieved the freedom to be free, the right not to be oppressed. We have not taken the final step of our journey, but the first step on a longer and even more difficult road. For to be free is not merely to cast off one's chains, but to live in a way that respects and enhances the freedom of others. The true test of our devotion to freedom is just beginning.

The scope and nature of the constitutional guarantee of the freedom of the press are to be viewed and applied in that light.

This quotation appeared in an article by Margaret Thatcher, "The Moral Foundations of Society" ( Imprimis, March 1995 https://imprimis.hillsdale.edu/the-moral-foundations-of-society/), which was an edited version of a lecture Thatcher had given at Hillsdale College in November 1994. Here is the actual passage from Thatcher's article:
<blockquote>[M]ore than they wanted freedom, the Athenians wanted security. Yet they lost everything—security, comfort, and freedom. This was because they wanted not to give to society, but for society to give to them. The freedom they were seeking was freedom from responsibility. It is no wonder, then, that they ceased to be free. In the modern world, we should recall the Athenians' dire fate whenever we confront demands for increased state paternalism.</blockquote>
The italicized passage above originated with Thatcher. In characterizing the Athenians in the article she cited Sir Edward Gibbon, but she seems to have been paraphrasing statements in "Athens' Failure," a chapter of classicist Edith Hamilton's book The Echo of Greece (1957), pp. 47–48 http://www.ergo-sum.net/books/Hamilton_EchoOfGreece_pp.47-48.jpg).
