.	From it I take it that there are three kinds
of items to consider:
1.	objects, including: 
	a.	material ones like rocks, cars and people; &amp;
	a.	immaterial ones like particular emotions,
	sensations, opinions, knowledge, whose attributes
	(including existence) are 4-D;
2.	relations between objects, whose attributes are 
	also 4-D, eg. friendship; and 
3.	time histories of objects and relations, and their 
	attributes, which are devoid of the traditional 4 dimensions;
