E=mc^2 has naught to do with Logic, of course, nor does the sequence of prime numbers (well, a little), so that point got lost. The earliest Lojban logo used intersecting circles (from Venn diagrams) and a doubled headed arrow (from one standard presentation of propositional calculus). But, of course, those are known only to people who have some acquaintance (however slight) to modern logic (since 1858 or so). Nothing universal springs to mind, since Logic, in this sense, at least, is an almost completely Euro-American phenomenon. There is a markedly different tradition in India (which might be symbolized with something picturing smoke on a mountain revealing fire). The early (and quickly quelled) Chinese tradition doesn't lend itself easily to depiction (how do you draw a
white horse not being a horse -- nor white?). The Islamic tradition transmitted and tidied up the Greek version to the West, which had received only a very dubious recension directly. So, as I said, this is a Western tradition and maybe we just have to face that an use Western logos -- not that I can think of one that really works for non-logicians.

Subject: Re: [lojban] New logo; a work in progress
As I said, it's a work in progress that needs opinions. So, here's the first question:
I symbolized logic using the 'E=mc^2' equation and a short sequence of prime numbers. But that doesn't seem to work. Like symbolizing language by the shape of some talking people, how do you symbolize logic in a culturally neutral way? And how do you symbolize the offspring; the Lojban language itself?
