What it comes to, then, is that the fundamental realities of nature are not, as thought construes them, separate things. The world is not a collection of objects assembled or added together so as to come into relationship with each other. The fundamental realities are the relations or 'fields of force' in which facts are the terms or limits - somewhat as hot and cold are the upper and lower terms (that is, termini or ends) of the field of temperature, and scalp and soles the upper and lower limits of the body.
Scalp and soles are obviously surfaces of the body, and though a person may be scalped, a scalp is never found sui generis, coming into being all on its own. But, save through the use of rather unsatisfactory analogies, words and thought forms cannot embrace this world. 'Relations' rather than 'things' as the basic constituents of nature sound impossibly tenuous and abstract, unless it can dawn upon us that relations are what we are actually sensing and feeling. We know nothing more concrete.
