There are a lot more in the canon. You can spend time following Immanuel Kant trying to painstakingly reason about morality from first principles. But I'd argue modern scientists and psychologists using empirical methods, like Jonathan Haidt, are far more interesting when it comes to morality. There's also the retarded ones that got everything wrong but are famous and important anyway, like Hegel and Marx.
