    You're correct that the proof does not refer to directed graphs.
    What I want to argue, rather, is that such graphs can be used to
    /visualize the meaning/ of the G||del sentence.

    ...

    In the graph you drew, (still in the quoted text above), each node is
    identical to the others.

    Yes, a "network" (or the DAG variant of a network) is required. A
    network is a graph with labelled nodes.



    That can get the evaluation of an expression stuck
    in an infinite evaluation loop on the basis of the
    cycle in its directed graph. Knowledge is acyclic.

    Knowledge is not acyclic. There are many kinds of telations between
    the parts of knoledge, as can be determiend by asking questions like
    "how do you know" and "where did you get the idea" and "what else
    does the same" and so on and analyzing the answers. Some of these
    relatoins lead to opposte directions.
