"Men and women don't just differ in terms of their genitalia, but in other important ways."
Simon Baron-Cohen is a clinical psychologist and director of Cambridge University's Autism Research Centre. He is known for formulating the mind-blindness theory of autism, which suggests that those with autism are somehow less able to "put themselves in other people's shoes".
He has made important and sometimes controversial interventions in a range of fields, and is well-known for his view - developed in his book The Essential Difference - that there exists an innate difference between the sexes.
