—  Marcus Tullius Cicero, De Inventione

Variant: Any man can make mistakes, but only a fool persists in his error.

“My opinion is this: the cause of the error of all these schools is their belief that God's knowledge is like ours; each school points to something withheld from our knowledge, and either assumes that the same must be the case in God's knowledge, or at least finds some difficulty how to explain it. …they likewise demonstrated… that our intellect and our knowledge are insufficient to comprehend the true idea of His essence. …they came to the absurd conclusion that that which is required for our knowledge is also required for God's knowledge.”

“Assuming the simulators, or at least the early generations of them, have a very advanced knowledge of the laws of Nature, it's likely that they would still have incomplete knowledge of them. …gradually the little flaws will begin to build up. …The only escape is if their creatures intervene to patch up the problems one by one as they arise.”

“The relationship of the suppliers and users of knowledge to the knowledge they supply and use is now tending, and will be increasingly tend to, to assume the form already taken by the relationship of commodity producers and consumers to the commodities they produce and consume--that is, the form of knowledge.”

“There are mistakes, which governments have been doing when they were trying to face the economic crisis, since 2008. Slow choices, sometimes insufficient, sometimes wrong, never neutral. Political choices made by political governments which must assume their responsibility on them. In Italy we have adopted forward-looking choices, economically speaking, we have adopted austerity as leading value. Now it is time to work on development and growth, to create jobs and exit this crisis.”

Federica Mogherini (1973) Italian politician

“My desire for knowledge is intermittent; but my desire to bathe my head in atmospheres unknown to my feet is perennial and constant. The highest that we can attain to is not Knowledge, but Sympathy with Intelligence. I do not know that this higher knowledge amounts to anything more definite than a novel and grand surprise on a sudden revelation of the insufficiency of all that we called Knowledge before — a discovery that there are more things in heaven and earth than are dreamed of in our philosophy.”

Henry David Thoreau (1817–1862) 1817-1862 American poet, essayist, naturalist, and abolitionist
