This is a video in my new Core Concepts series -- designed to provide students and lifelong learners a brief discussion focused on one main concept from a classic philosophical text and thinker.
This Core Concept video focuses on Plato's work, The Republic and specifically on his discussion in the end of book 6 of the "Divided Line". This analogy is used to arrange the matters human beings can grasp and (in some cases) develop knowledge about, ranging from those that posses the least truth and being to those that possess the most.
The four parts of the line include: 1. he domain of shadows, reflections, and other things of that sort; 2. the domain of "real", material, generally visible, objects, such as animals, plants, and human-produced artifacts; 3. some of the forms, those that are grasped to some degree through likenesses; and 4. the forms grasped on their own terms, and the Form of the Good.
We also have four modes of grasping these objects. Eikasia, "imagination" or "picture thinking""; Pistis, "belief"; Dianoia, "discursive thinking"; and Noesis, "understanding" or "intellection".

    Well done. A pity Wittgenstein didn't spend more time with the Greeks. Plato's ideas on images (picture thinking?) reminded me of Wittgenstein's first philosophy. Both were concerned with the limits of what can understood.

    that's so true. yea Wittgenstein didn't bother to read a lot of stuff unfortunately I guess because he thought he already figured the whole "philosophy thing" out.

    Tough, the distinction between Dianoia and Noesis. One could postulate the descending spirit of the Logos. One could postulate the knowledge of the discursive power itself, to arrive at absolute nature by that of Forms as governing rationality. There is evidently in arriving at the Forms in Dianoia the problem of logical extension. That logical extension is an expression of the soul in that rationality is chained to the soul by means of corporeal being. Noesis must, to be higher, it ought be a refinement of the intellect and an active function of a universal utilitarian language and integrated symbolic logic of technical competence. In some ways the divided line is an imperfect understanding since that which permits the fullest understanding is that which is in a condition of being wise in the apprehending of being in relation to matters. This also questions what matters are concrete or merely adequate or sufficient for some but not others. The divided line in terms of function could be the metric for a Philosophers' IQ. Not at least for the sake of musings.

    I think the process of going through dianonia and noesis is continuous. Since in a dialectic we are expected to stop somewhere and we have to start again working on the basics digging deeper.

    Depends on whose version of "dialectic" you have in mind. In order to understand Plato, you won't want to import any ideas about that term from much later thinkers

    Would this suggest in the highest end of the line there is a knowledge in everyone of everything that ever was or ever will be and only when something is first invented for example the person had unlocked or discovered it and moved it into a lower part of the line where is can become a form in which the material can be seen? Thank you for your videos I actually find the dialogue of the republic really difficult to keep track at times and videos like this help to explain or reassure what I believe is being expressed. Like you said the concepts in itself are not always difficult but drawing them out of the dialogue is not always easy

    @@GregoryBSadler ha. or, if you have plunged into nihilism and have given up on all teleological religions.... at least the Forms are something real. If you are raised in an environment with teleological religion, and then you no longer feel that it is real , and you still need some kind of meaning to get out of bed in the morning... :) // living in nihilism is a challenge because the trappings of culture which usually give so much support no longer give impetus along a narrative. Or, maybe i am reading too much into Plato's Forms.

    I wouldn't try to lump all religion into one category like that. And if you're trying to do without religion, and substitute philosophy instead, Platonism might be one option (though you'd want to go beyond just Plato, if that's the case), but just one among many. And pretty much all of those options are going to be "teleological"

    I don’t believe most know the divided line even exists or rather that anyone can grow closer to “reason”. People are not willing to listen to certain types of people, or anybody but themselves. The ones that know that they do not know are the ones that will aspire to grow closer to Noesis because they can’t help themselves. They are aware. It will always be a means for the ones who know of it. Hopefully
