Quotes & Sayings About Learning From Mistakes In History

Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science - by far the most successful claim to knowledge accessible to humans - teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. — Carl Sagan

But the history of science - by far the most successful claim to knowledge accessible to humans - teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error bars a little, and to add to the body of data to which error bars apply. The error bar is a pervasive, visible self-assessment of the reliability of our knowledge. — Carl Sagan

Everything has happened before - not once, but over and over again. We may not be able to solve our problems through what are pompously called "the lessons of history," but at least we should be able to recognize the issues and perhaps avoid some of the solutions that have failed in the past. And we can take heart in our own dilemma by realizing that other people in other times have survived worse. — Elizabeth Peters

Will this generation be able to turn things around and learn a valuable lesson from all of this? I hope so, but I have my doubts. The damage has been done. And as a lifelong student of history, it's quite evident that human beings don't learn from the mistakes of past generations. — Aaron B. Powell

The philosopher and historian George Santayana once remarked that those who do not know their history are doomed to repeat its mistakes. A perusal of some of the essays will reveal that this is not always true. In some cases psychologists have known about mistakes of the past and sought to repeat them. But the recurrence can sometimes be fruitful: going round in circles can be a good thing, provided the circle is large that when one returns to the task one sees it in a new light and the error brings new insights. — Noel Sheehy

Learning from history helps us avoid repeating its mistakes. — T.A. Uner
