How does plato distinguish between knowledge and belief? How is it based in his metaphysics?

  • Interestingly, we have no question with the Plato tag on this topic. We do have one two terms for knowledge in Plato: philosophy.stackexchange.com/questions/7789/…

  • Also, is this question for a class? (I ask because it's exceptionally clear and precisely the sort people tend to get asked in classes)

  • It is not for class but rather for a test that is very important for me. If that is not allowed then i'm sorry. I didn't know about it. I couldn't find a good answer so i posted it here. Commented Sep 12, 2015 at 11:28

    Class-related questions are not disallowed (= they are permitted), but some of our members prefer not to be involved in these sorts of questions, and it helps to disclose this sort of thing.

  • @Kartikay Sharma How about this PLATO: TRUE BELIEF AND KNOWLEDGE IN MENO AND THAEATETUS definitionofphilosophy.blogspot.com/2012/09/… That's how one knows to change essay topics for class, when ready made essays are posted online.

If you read the site below, you will have a pretty decent understanding of Plato on this topic: http://plato.stanford.edu/entries/plato-theaetetus/

A quote from the site states:

Theaetetus' third proposal about how to knowledge is (D3) that it is true belief with an account (meta logou alêthê doxan).

This is where we get the statement: Justified True Belief is Knownledge

You can also state the equation with three sentences: S knows that p eff:

  1. p is true;
  2. S believes that p;
  3. S is justified in believing that p.

I hope this helps

    At least in early and mid Plato, it would not at all be accurate to equate knowledge with justified true belief.

  • @virmaior if you read Theaetetus, he clearly makes this connection

    Perhaps, but my comment was merely that early middle Plato doesn't draw this connection and Theaetetus is late Plato.
