Leaving Hegel aside, (or wherever he is now, which is either Nowhere or in not a very comfortable place to be) there appears to be something Zen Buddhist about the answer {{}} that Solve returns when given a tautological equation, like: In[1]:= Solve[x==x,{x}] Out[1]= {{}} The answer looks like "nothing", but in some sense it also means "everything". In other words, Nothingness ==The Universe == The Absolute, etc, etc... (I guess that means that the union of {{}} and {{x->0}} ought to be indeed {{}}, except that in this particular problem {{}} was a False Absolute or False Nothingness, oh well...) Andrzej
