He was my "personal tutor" at Balliol College Oxford, after I switched from mathematics and logic to philosophy. He was very kind to me personally, including inviting me to join him, his family, and his students on a trip to Plas Rhoscolyn in Anglesey, and giving me some of his time to discuss philosophy, despite my being fairly ignorant of most philosophy. He eventually even trusted me to give tutorials on moral philosophy to some of his students, while I was working on my D.Phil.
I also went to lectures and seminars by other Moral philosophers in Oxford, including Elizabeth Anscombe and Philippa Foot, both of whom disagreed strongly with Hare's meta-ethics. Although I liked and admired both, I thought then, and think now, that Hare was more right than they were: they both struck me as being guilty of wishful thinking, since they did not like the conclusions of his arguments and tended to use scorn rather than reason in opposing him. But I also thought Hare guilty of wishful thinking in supposing that his prescriptivist analysis of "good" and "ought" could provide a basis for arguing rationally against fanatics like Hitler or South African white supremacists.
I later concluded that "better" was the most basic concept and wrote some papers on the implications of treating "better" as a sort of logical operator with multiple arguments.
