FOM: a phrase

[Kanovei]

a lot of the book discusses the category of directed graphs instead.  In
particular, it discusses truth-value objects in this context, and 
*I found that useful* 
(the first example of these things that I really liked)
*largely because it was so different from the usual set theory*.

The emphasized (by myself) phrase, 

*I found that useful 
 largely because it was so different from the usual set theory* 

is far the best brief statement by proponents of the 
"categorical foundations"
