Virginia Woolf, in the 1920s, made the point: 'It is obvious that the values of women differ very often from the values which have been made by the other sex. Yet it is the masculine values that prevail' remade sixty years later by psychologist Carol Gilligan who used it to show that psychological tests of maturity have generally been based on masculine parameters, and so tended to show that women were less 'mature'. Gilligan countered this in her ground-breaking work, "In a Different Voice", holding that maturity in women is shown in terms of different, but equally important, human values.
