One of the biggest challenges of our time is not people without morals, according to philosopher Tim Dean. It is often those with unwavering moral convictions who are the most dangerous. Tim challenges us to change the way we think about morality, right and wrong, to be more adaptable in order to solve the new and emerging problems of our modern lives. Tim Dean is a Sydney-based philosopher and science writer. He is the author of How We Became Human, a book about how our evolved moral minds are out of step with the modern world. He has a Doctorate in philosophy from the University of New South Wales on the evolution of morality and has expertise in ethics, philosophy of biology and critical thinking. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
