Hmm.=A0 Just some rough thoughts.=A0 For representing "logic" = the most basic/fundamental concept is the law of identity pe'i.=A0 So w= hat about something like:
X=3DX
Or some such. Maybe some symbol other than "X" if a different sym= bol would look better?

Subject: Re: [lojban] New lo= go; 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=3Dmc^2' equation and a short s= equence of prime numbers. But that doesn't seem to work. Like symbolizi= ng language by the shape of some talking people, how do you symbolize logic= in a=A0culturally=A0neutral way? And how do you symbolize the offspring; t= he Lojban language itself?
