If all knowledge were eradicated, what one principal or theory would you retain as the most valuable?

Observe\nHypothesize\nCheck\nRevise Hypothesis\nRepeat\n\nThat is how we created all the rest of our knowledge, it is how we could re-create it if all other knowledge were lost

for the historical precedent and legacy it left, would have to give it to citizen kane.  \n\nfor sheer entertainment and production value, a toss up between shawshank and godfather 2, with a slight advantage to shawshank.

If i were you, I would choose the neolithic revolution and then the bubonic plague.\n\nI'll give some contentions as to why:\nNeolithic revolution - set foundations humans built upon. first agricultural societies which led to sedentary developments. Without it we'd all be nomads scouring the land for food with no domesticated crops or animals.\nBubonic Plague - Killed off 40% of the population and led to a decrease in serfdom and an increase in wages for competant workers were harder to find (supply and demand) World before plague was at a population it wouldn't reach until at least 200 years after it.

Anything is possible.  We're talking about something that happened a long time ago.  The only thing we had left is what someone wrote down.  At some point in time anyone could delete/add anything.

I would say Watson and Crick.  They discovered DNA, leading the biological world into a whole new era that makes so much possible from treating deadly diseases to cloning.

Ben Franklin.  Ahead of his time, creative in multiple fields from science to diplomacy, apparently a great conversationalist.\n\nThis is a fairly common question, but a great one nonetheless when the person can be dead or alive. Another version of the question asks you to name 3 people, dead or alive, who can come from different historic times.  Would be fun to pair up Franklin with Da Vinci, for example.  Hard for me to choose the 3rd one, though.  If I had to choose, I'd also invite Shakespeare, but there are many others.

oh, I'd say the Bible :-)

Because you will always retain some knowledge, who knows one day a fact stored in the deepest recesses of your mind, could mean the difference between life and death, success or failure. \nKnowledge is never wasted.

The best lesson we can learn is the immutable law most aptly set down by George Santayana:  "Those who do not learn from the past are condemned to repeat it."\nEspecially those who quack out the same old tired slogans about how religion can solve all of our problems...

I would eliminate the whole thing. See the reference below:

Full Metal Alchemist\nhttp://www.fullmetalalchemist.com/flash_index.html\n"Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is alchemy's first law of Equivalent Exchange. In those days, we really believed that to be the world's one, and only, truth." \n— Alphonse Elric

Plato for sure... I was just re-reading the Republic recently and admiring all over again how very well he picked an issue apart by answering every question with another question until getting to the root of it. If only we all did that!

I took economics in college.  The professor made an observation you might like:  "If you took all the economists in the world, and put them end to end, you still wouldn't reach a conclusion."

Knowledge, instead of ignorance!\nHuge benefit!
