Bettina Mary Arndt (born 1 August 1949) is an Australian writer and commentator who specialises in sex and gender issues. Starting as a sex therapist and feminist, she came to public prominence in the 1970s, establishing a career in publishing and broadcasting as well as writing several books. In the last two decades she has abandoned feminism and attracted controversy with her social commentary and her views on sexual abuse, domestic violence and men's rights advocacy.

We look for medicine to be an orderly field of knowledge and procedure. But it is not. It is an imperfect science, an enterprise of constantly changing knowledge, uncertain information, fallible individuals, and at the same time lives on the line. There is science in what we do, yes, but also habit, intuition, and sometimes plain old guessing. The gap between what we know and what we aim for persists. And this gap complicates everything we do.
