Very frequently  feminine activity also expresses itself in what is largely a retrospectively oriented pondering over what we ought to have done differently in life  and how we ought to have done it  or  as if under compulsion  we make up strings of causal connections. We like to call this thinking  though  on the contrary  it is a form of mental activity that is strangely pointless and unproductive  a form that really leads only to self-torture.
