Alan Moore on Anarchism (2009)
Context: Fascism is a complete abdication of personal responsibility. You are surrendering all responsibility for your own actions to the state on the belief that in unity there is strength, which was the definition of fascism represented by the original roman symbol of the bundle of bound twigs. Yes, it is a very persuasive argument: “In unity there is strength.” But inevitably people tend to come to a conclusion that the bundle of bound twigs will be much stronger if all the twigs are of a uniform size and shape, that there aren’t any oddly shaped or bent twigs that are disturbing the bundle. So it goes from “in unity there is strength” to “in uniformity there is strength” and from there it proceeds to the excesses of fascism as we’ve seen them exercised throughout the 20th century and into the 21st.
Now anarchy, on the other hand, is almost starting from the principle that “in diversity, there is strength,” which makes much more sense from the point of view of looking at the natural world. Nature, and the forces of evolution — if you happen to be living in a country where they still believe in the forces of evolution, of course — did not really see fit to follow that “in unity and in uniformity there is strength” idea. If you want to talk about successful species, then you’re talking about bats and beetles; there are thousands of different varieties of different bat and beetle.

Heretics and Heresies (1874)
Context: Every church pretends that it has a revelation from God, and that this revelation must be given to the people through the church; that the church acts through its priests, and that ordinary mortals must be content with a revelation — not from God — but from the church. Had the people submitted to this preposterous claim, of course there could have been but one church, and that church never could have advanced. It might have retrograded, because it is not necessary to think or investigate in order to forget. Without heresy there could have been no progress.

A Grief Observed (1961)
Context: Can a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are there in a mile? Is yellow square or round? Probably half the questions we ask — half our great theological and metaphysical problems — are like that.

Variant translations:
Zeus has led us on to know,
the Helmsman lays it down as law
that we must suffer, suffer into truth.
We cannot sleep, and drop by drop at the heart
the pain of pain remembered comes again,
and we resist, but ripeness comes as well.
From the gods enthroned on the awesome rowing-bench
there comes a violent love.
Robert Fagles, The Oresteia (1975)
God, whose law it is
that he who learns must suffer.
And even in our sleep, pain that cannot forget
falls drop by drop upon the heart,
and in our own despite, against our will,
comes wisdom to us by the awful grace of God.
Edith Hamilton, The Greek Way (1930), pp. 61 and 194 ( Google Books https://books.google.com/books?id=D3QwvF3GWOkC&lpg=PA61&ots=BacvHvGm6e&dq=%22And%20in%20our%20own%20despite%2C%20against%20our%20will%2C%20Comes%20wisdom%22%20-kennedy&pg=PA194#v=onepage&q=%22our%20own%20despite%22&f=false)
Robert F. Kennedy quoted these lines in his speech announcing the assassination of Martin Luther King, Jr. on 4 April 1968. His version http://www.americanrhetoric.com/speeches/rfkonmlkdeath.html:
Even in our sleep, pain which cannot forget
falls drop by drop upon the heart
until, in our own despair, against our will,
comes wisdom through the awful grace of God.
Variant translations of πάθει μάθος:
By suffering comes wisdom.
The reward of suffering is experience.
Wisdom comes alone through suffering.
