 Many more questions centred around these five philosophical themes remain to be examined in relation to conceptual art. With regards to concerns about defining art, we need to address the increasing number of worries to do with exactly how we are to distinguish art from non-art, and indeed whether there really is a distinction (if only theoretical) to be drawn here. That is to say, if conceptual art is at times not only perceptually indistinguishable from non-art but it is also the case that everything is alleged to be (part of) a potential artwork, perhaps the inevitable outcome is that there simply cannot be a principled distinction between art and non-art. So, does the conceptual project lead to the end of the category of art as such?
