What element of greek tragedy does ismene articulate in the following lines from antigone?

'tis foolishness, i ween,
to overstep in aught the golden mean.

This testifies the low power of the women to fight against the state. Antigone displays anagnorisis and feels that what they were told is not right and what her sister is telling her is not right and she should fight. Her sister wanted Antigone to obey the law so that she could not get jailed, but Antigone realizes the real truth.
