    “[My mother told me:] “You must decide whether you want to get married someday, or have a career.”... I set my sights on the career. I thought, what does any man really have to offer me?”

    “... the first reason for psychology’s failure to understand what people are and how they act, is that clinicians and psychiatrists, who are generally the theoreticians on these matters, have essentially made up myths without any evidence to support them; the second reason for psychology’s failure is that personality theory has looked for inner traits when it should have been looking for social context.”
    —Naomi Weisstein (b. 1939)
