As I said the first time, a table is a real concept because it has all sorts of intrinsic properties and actions directly associated with it; 4 legs, a table-top, and people like to have them in their houses and put objects on them. Whereas red doesn't have any of this, other than just existing. It may be someone's favorite colour, but that doesn't affect red itself, merely that person's conception of red.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6642011.post-1085225018378836042004-05-22T07:23:00.000-04:002004-05-22T07:23:00.000-04:00Fair enough (I would tend to agree, actually, sinc...Fair enough (I would tend to agree, actually, since I think if you accept <I>any</I> universals you should really accept them <I>all</I>).<br /><br />But why deny the reality of redness? Surely we can picture redness, at least as well as we picture unicorns. We can also talk about it as an abstract noun, e.g. "Red is my favourite colour". And it really doesn't seem plausible that, when pointing to a red table, saying "this object is a table" is relevantly different from saying "this object is red". (Red may be more 'basic', as previously discussed, but I'm not sure why that is a <I>relevant</I> difference here?)<br /><br />So why are you wanting to say that redness is not a real property? (I don't mean to be 'attacking' here, I'm genuinely curious about what reasons you have for making this distinction.)Richard Y Chappellhttps://www.blogger.com/profile/16725218276285291235noreply@blogger.comtag:blogger.com,1999:blog-6642011.post-1085214610689619512004-05-22T04:30:00.000-04:002004-05-22T04:30:00.000-04:00I disagree with it needing a real example in order...I disagree with it needing a real example in order for it to be a real concept.<br /><br />Books and literature have unicorns in them, and when someone says "unicorn" you get a fairly certain picture of what they mean, just like when someone says "table".

I disagree wit...Yeah, that is an interesting idea. I disagree with it - but it <EM>is</EM> interesting :)<br />I don't see any logical inconsistencies in it. It's just a bit odd to say that an aggregation of non-existent properties could be any more real than the parts from which it is made.<br /><br />There's also the problem that your assertion that "Red has no properties" is - technically - false. For example, it has the properties of 'being a property', 'being non-corporeal', 'being non-existant' (according to you ;)), and infinitely many others can be constructed along the lines of 'being zero or not-zero', etc.<br /><br />But I think I get the idea of what you mean, it's just difficult to express it precisely (in such a way as to avoid trivial objections such as the previous paragraph). Correct me if I'm wrong, but I think what you mean is that a concept is real if it is <B>appropriately constructed</B> out of other, more basic, concepts (which may or may not be real). [Thus you could say that 'red' is not real, because it isn't "appropriately constructed" out of the trivial properties I mentioned above.]<br /><br />This produces a new problem, in that you seem to be forced into asserting that unicorns are more real than colours. After all, the concept of 'unicorn' is appropriately constructed out of other concepts (i.e. horses and horns), in exactly the same way that the concept 'table' is constructed from more basic parts. So you might want to add in an extra condition to the effect that a 'real' concept must have at least one real-life instance/exemplar.<br /><br />So, with a bit of work, I think your theory could be made reasonable. But I'm not really too sure whether it's worth it. That is, I'm not convinced that we should want to say that complex concepts (eg 'table') are any more real than basic concepts (eg 'red'). I just don't see what the motivation for such a distinction would be.<br /><br />For myself, I'd probably prefer one of the following two extremes:<br /><br /><B>1) Full-blown Platonism:</B> Every possible universal concept necessarily exists (outside of space & time), from 'red' to 'table' to 'unicorn'.<br /><br /><B>2) Austere Nominalism:</B> No universals exist, only particular objects exist. When we say two objects are both 'tables', all we really mean is that they have a relevant similarity that makes it worthwhile for us to group them together. They don't actually share any metaphysical 'essence' though.<br /><br />There is a nice compromise called 'trope theory', which I might blog about some time soon though (I think our metaphysics lecture on Monday will be about that).Richard Y Chappellhttps://www.blogger.com/profile/16725218276285291235noreply@blogger.comtag:blogger.com,1999:blog-6642011.post-1085133490466504952004-05-21T05:58:00.000-04:002004-05-21T05:58:00.000-04:00This is Greg, obviously. I just can't be bothered ...This is Greg, obviously. I just can't be bothered making an account (I like the Haloscan comments more, actually).<br /><br /><br />I was thinking about our talk and the idea of red not being real, whereas the idea of a table was. Specifically what you said about the table being made up of things that aren't real, wouldn't that require that the table also not be real?<br /><br />I think I've more clearly clarified my thinking here, but it's probably not consistent. I'm not great at this sort of thing, so if you can see a flaw, feel free to point it out :)<br /><br />Anyway, suppose we have Red, which is not a real concept, in that it has no other properties, and when you think of the concept 'red' you likely think of an item that has its colour property = red. There is no concrete 'red' itself, only some kind of representation of it - a red ball, or a graph of the wavelengths of light with one section circled. I'm not entirely sure if this makes sense, when compared to the concept of table. Are you actually imaging the real concept 'table', or are you simply imagining a specific example of table? The latter would seem just to be the same as your imagining of red, really, yet I'm calling red 'non-existent' and table 'existent'.<br /><br />Anyway, I'll go on from that shakey basis:<br /><br />Red is not real, but a rainbow is. A rainbow consists of roughly 7 colours, which don't exist. So you would think that anything that consists entirely of things that don't exist, must also not exist. Which is where I throw in the idea of aggregation. Anything that is an aggregation of properties, is real, whereas anything that isn't, is not real. So red does not have any properties other than it itself being a property. But a rainbow would have the properties of having 7 colours, which is an aggregation, so it would be a real concept.<br /><br /><br />The more I think about this, the more I think that this arguement is horribly flawed and silly, but oh well, interesting to consider, at least, I think.Anonymousnoreply@blogger.com
