Our present alphabet was put in this order by a single person (If I recall properly an article I read many years ago). This is not essential here though. There are universal principles at work.
This analysis has possible significance only with the lower case. The upper case is of uniform height and is more of a standardized "power trip" than an insite on the human condition. This applies to the history of man rather than present conditions in an advanced Western type civilization.
bdpq are clearly phallic symbols.
In the first group bcd a c is inserted between two erections indicating a conflict over what? (obviously a woman - c__t?). The two arms are reaching toward the more mature d (dad?) and her back is turned to the b (boy?). This is a conflict of two men over a woman with the more powerful, dominant male getting the female.
efg looks like a family group. The e is a small child ... f is the father ... g is interacting with f trying to obtain a handout from f.
hijk is the familiar
where the dots from i and j are eyes and the rest of the i being a teardrop ... and the j - a nose ... while the k is the mouth.
h looks like a horse, eh? Maybe. I don't know what significance this may be. Perhaps a female offering dogstyle???
What we have here is a rather meek and mild philosophy
I once had an idea for what the no stood for with a relaxed papa looking on ... but I've forgotten what it was. Sorry. I believe the n is a frown ... mouth corners down.
w x and y and z
This is philosophical commentary ...
burned into our collective subconscience and finding its expression in much of what we do ... including even our alphabet. It is reminiscent of "Ring around the rosy, a pocket full of posy, ashes, ashes ... all fall down" ... a child's view of the plague circa 17th century.
I don't think I'm making it up entirely on my own, eh?
