 On the whole, the philosophical concerns raised by conceptual art can be divided into two main categories. First, there are specific questions to do with conceptual art itself, and the claims which underpin the project that drives it. Philosophical investigations might thus be called for not only in relation to the internal consistency and coherence of the project and its set goals, but also with regards to the particular tenets outlined above. For example, what does it mean to say that every single thing, person or event is a possible candidate for an artistic medium and does that suggestion not render the category of art, as we know it, redundant?
