 Concerning (2), note that to represent space by representing it through other concepts may require one to take a (usually controversial) stand on the ontology of space in one of the senses outlined above. For instance, if one wishes to place &lt;space&gt; somewhere on the conceptual tree, one must presumably find a place for it under some concept such as &lt;substance&gt; or &lt;being&gt;. But there is no accepted view of space’s ontology: some regard it as a substance (or a being), others as a network of relations, others as a property of God, etc. Because of these long-standing, unresolved disputes, it seems reasonable to regard an approach that depends on their resolution as unpromising. Kant highlights the accepted fact that we represent space as an infinite Euclidean magnitude—this can be widely accepted, despite the dispute concerning space’s ontology.
