Socrates Plato Aristotle | World History | Khan Academy

"It is the mark of an educated mind to be able to entertain a thought without accepting it." I love that quote, almost forgot about it.

"Places of learning have become known as academies - just like Khan academy" We have come full circle

amazing teaching style! can't thank you enough!

you find the greatest and most thought provoking quotes. thank you

How can anyone dislike this lecture? It is a very succinct introduction to three of the greatest thinkers to have ever lived.

You've misattributed to Aristotle, the quote: "It is the mark of an educated mind to be able to entertain a thought without accepting it." The quote has merit, but Aristotle never said anything like this. If you look up the nearest thing to this quote in Aristotle's Nicomachean Ethics, book one (1094b23-25), you will see that the actual quote is (loosely translated) "It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible." We rely on Khan for clarity, accuracy and quality education. Please don't let us down.

Thank you so much for this lesson!

i love khan academy its so helpful thx khan academy

bear in mind that, while Aristotle may have been a student at Plato's academy, he was exactly the opposite of him in terms of philosophy, to such the extent that, despite being a prodegy and the very best srudent, he was refused Plato's position after his death because he didn't believe in his "forms". While the academy spent all it's time constructing geometric proofs on what an ideal chair would be, the Lyceum would actually look at, and document particular qualities of good chairs.

Excellent video, content and delivery. Thank you.

Man, did I ever laugh out loud at 4:15 ! Good one, Sal!

When you spoke about Socrates' fears of true democracy I imagined our current situation in American politics!

Thanks helped a lot learning this

Could you make a video explaining the Cathode Ray Tube and how it works?

The Socratic Method was one of the most controversial-Socrates used to go out into the market-space and ask a random stranger about their theory about ethical issues, such as lying. Often, he turned conventional ideas upside down-a charge that was phrased as angering the goods (or not believing in them) in his death sentence by poisin.

Thank you so much!!

"Prawdziwa wiedza przychodzi do nas, kiedy zdajemy sobie sprawę, jak niewiele wiemy o życiu, o nas samych i otaczającym nas świecie."
