 Among those who do not doubt the coherence of the concept of intrinsic value there is considerable difference of opinion about what sort or sorts of entity can have such value. Moore does not explicitly address this issue, but his writings show him to have a liberal view on the matter. There are times when he talks of individual objects (e.g., books) as having intrinsic value, others when he talks of the consciousness of individual objects (or of their qualities) as having intrinsic value, others when he talks of the existence of individual objects as having intrinsic value, others when he talks of types of individual objects as having intrinsic value, and still others when he talks of states of individual objects as having intrinsic value.
