Hello Mr Morrison,
I think the issues are discussed quite thoroughly on the other thread, mentioned by John Seavitt.
There is a very good discussion of the origin of Chinese writing in the Cambridge History of Ancient China.
The essay is "Language and Writing", by William G Boltz. The three stages in the evolution of Chinese script are worth special attention.

PS. Give my best wishes to Sean MacR.
I usually take suki to mean an opening for a technique. What is the kanji for, and the meaning of, suki?
From a short search on-line, http://jisho.org/kanji/details/%E9%9A%99
, I got 隙 with the possible meanings
1: gap; space;
2: break; interlude; interval;
3: chink (in one's armor, armour); chance; opportunity
with 隙 made from the parts
Is this the character usually used? If so how do the the three symbols combine to mean suki?
