Actually, John, the last observation is slightly inaccurate.  'give' is a 
predicate.  A is not connected to 'give' but rather to some "event" x that 
satisfies 'give', and similarly, B and C.  Moreover, the 3 dyadic relations 
capture the notion of distinct "roles" in the 'give' event.  I prefer to speak 
of the existentialized event x as a "giving" (the gerund).  It is my 
recollection that Adam Pease also explicitly uses the term 'gerund' in 
describing the CELT (KIF) model of A gives B to C.    (01)

Two points:    (04)

1. It is certainly true that you can map A gives B to C into a form that uses 
only dyadic relation.    (05)

2. But Peirce was trying to explain that you have simply converted one triad 
into a triad of a different form.    (06)

I'll just use predicate calculus notation, since it's easy to type.  But the 
point is obvious when you use a graph notation.    (07)

With a triadic relation:    (08)

     gives(A,B,C)    (09)

With three dyadic relations and a monadic relation give(x):    (010)

     (Ex) give(x) & agent(x,A) & theme(x,B) & recipient(x,C)    (011)

In the first version, you have a triadic connection of A, B, and C to the 
relation named gives.    (012)

In the second version, you have a triadic connection of A to agent to give, B 
to theme to give, and C to recipient to give.    (013)

You still have a triad, but the central node is called give instead of gives.    (014)
