Sufficient assumptions | Worked example

Video transcript

anyone who believes in democracy has a high regard for the wisdom of the masses gray how ever is an elitist who believes that any artwork that is popular is unlikely to be good thus gray lead is not believed in democracy the conclusion follows logically if which one of the following is assumed so before I even look at this let's just try to deconstruct what this what the author is trying to say because it it does seem to jump make a pretty big logical leap so even if you accept what they're saying this first statement anyone who believes in democracy has a high regard for the wisdom of masses so they're saying anyone who believes in democracy well they're going to be a subset of the people have a high regard for the wisdom of masses so let's say these are the folks who believe in democracy believes in democracy so let's say that circle is all of the people who believe in democracy and they're saying anyone who believes in democracy has a high regard for the wisdom of the masses so anyone who believes in democracy has a high regard for the wisdom of masses so that means that all of these people have to have a high regard for the wisdom of the masses now they're not saying that everyone with a high regard for the wisdom of the masses believes in democracy so maybe the people with the high regard for the wisdom of masses they is a super set so high regard for mass wisdom or mass wisdom so anyone who believes in democracy will also be in the set of people who have a high regard for mass wisdom so then they go to talk about dryly dryly however is an elitist who believes that any artwork that is popular is unlikely to be good so there's statement there making the statement about gray Lee and they're saying that he's an elitist so there first of all they're just calling him a name but then they say who believes that any artwork that is popular so popular popular art if he sees or she I don't know gratis a he or she but grimy if they see popular art then they think it unlikely to be good unlikely unlikely good and obviously these are all things that someone else is saying is true about grilling but even if you accept all this they then make this conclusion or the statement the scry Li does not believe in democracy which feels like a bit of a jump kryla does not believe in democracy so something about this red this red statement about ground Rylee somehow in this author's mind definitively puts gray lee either definitely not in this circle one someone who does not believe in democracy either in this one where Grindley maybe has a high regard for mass wisdom but does not believe in democracy or is even sitting out here someone who does not have a high regard for massed wisdom well then they're definitely not going to believe in democracy so somehow they're trying to connect someone who thinks that if artist popular is unlikely good to sitting in one of these places where you wouldn't believe in democracy so let's see if any of these key assumptions could help us there and one way to imagine is test if this was part of the original statement whether it would make a little bit more logical sense so see part or choice a anyone who believes that an artwork is unlikely to be good if it is popular is an elitist well no this would just justify the name-calling that they're saying where they sing you know why they're calling growly and elitist but it doesn't back up this connection where if someone believes that something is popular it's unlikely to be good that that is somehow connecting to someone who does not believe in democracy this is just justifying calling someone and elitist so I'd rule that one out anyone who believes that is that if an artwork is popular is unlikely to be good and they're saying that that is true of growley that's this red part right over here does not have a high regard for the wisdom of the masses so if if this is assumed if choice B here is assumed then this statement about gray Lee which the passage does make it with it puts gray Lee on this dot right over here outside of the set of people have a high regard of mass for the masses and if someone does not have a high regard for mass wisdom then they for sure are not going to believe in democracy and so you this choice is actually looking pretty good if we added this to our original passage the passage would make a little bit more sense let's try that out anyone who believes in democracy has a high regard for the wisdom of the masses Grindley however is an elitist who believe that any artwork that is popular is unlikely to be good anyone who believes that if an artwork is popular is unlikely to be good does not have a high regard for the wisdom of the masses and so they don't have a high regard for the wisdom of the masses then they're definitely not going to be in this orange set which means that they're for sure not going to be in this blue set that believes in democracy so I definitely like choice B now let's see choice C if gray is not an elitist then he has a high regard for the wisdom of the masses well this is a little bit beside the point once again like choice a focusing on the word elitist and the saying if he is not an elitist then he has a high regard for the wisdom of the masses so if you're not an elitist they're saying that you're at least going to be in this orange one maybe you're in this blue one but it doesn't even if this was assumed you could still have elitist that have high regard for the wisdom of masses might which might be a little bit against the word elitist but this doesn't really solidify the logical chain going on here choice D anyone who does not have a high regard for the wisdom of the masses so that's anyone outside and outside of the orange here is an elitist so is an elitist who believes that if an artwork is popular it is unlikely to be good well that's saying okay someone's out here might be an elitist and they might have views on art like Riley but it's not ruling out the possibility that gray Lee couldn't necessarily be in here so I don't like this choice either unless Briley believes in democracy gray leader XIV a high regard for the wisdom of masses so unless gray Lee is here unless he believes in democracy karate does not have a high regard for the wisdom masters now what's the problem with this is you're still not making a connection between this statement this popular art that they're claiming that growley thinks of something it's unlikely good this one still doesn't make the connection between that and high regard for the wisdom of masses or belief in democracy so it doesn't connect the two parts of the statement still so I would rule that out and I feel really good about twice be
