A third possibility is rarely expressed: that women tend to adopt a certain kind of psychology which makes them less functional, in many areas, than men.
Two thousand years ago, somebody appears to have expressed the idea that women had the same potentialities as men, but could only realise them by adopting male psychology.
Simon Peter said to them: ‘Let Mary go out from among us, because women are not worthy of the Life.’
Jesus said: ‘See, I shall lead her, so that I will make her male, that she too may become a living spirit, resembling you males. For every woman who makes herself male will enter the Kingdom of Heaven.’
(Gospel of Thomas, saying 114)
