It has already been emphasised that an actual occasion is to be conceived as a limitation; and that this process of limitation can be still further characterised as a gradation. This characteristic of an actual occasion (α, say) requires further elucidation: An indeterminateness stands in the essence of any eternal object (_Α_, say). The actual occasion α synthesises in itself every eternal object; and, in so doing, it includes the _complete_ determinate relatedness of _Α_ to every other eternal object, or set of eternal objects. This synthesis is a limitation of realisation but _not_ of content. Each relationship preserves its inherent self-identity. But grades of entry into this synthesis are inherent in each actual occasion, such as α. These grades can be expressed only as relevance of value. This relevance of value varies—as comparing different occasions—in grade from the inclusion of the individual essence of _Α_ as an element in the aesthetic synthesis (in some grade of inclusion) to the lowest grade which is the exclusion of the individual essence of _Α_ as an element in the aesthetic synthesis. In so far as it stands in this lowest grade, every determinate relationship of _Α_ is merely ingredient in the occasion in respect to the determinate _how_ this relationship is an unfulfilled alternative, not contributing any aesthetic value, except as forming an element in the systematic substratum of unfulfilled content. In a higher grade, it may remain unfulfilled, but be aesthetically relevant.
