 Similarly, many philosophers take a platonistic view of  properties.  Consider, for instance, the property of being red. According to the platonist view of properties, the property of redness exists independently of any red thing. There are red balls and red houses and red shirts, and these all exist in the physical world. But platonists about properties believe that in addition to these things, redness — the property itself — also exists, and according to platonists, this property is an abstract object. Ordinary red objects are said to exemplify or instantiate redness. Plato said that they participate in redness, but this suggests a causal relationship between red objects and redness, and again, contemporary platonists would reject this.
