Coming to philosophy of education from educational psychology I found working with John White invigorating and freeing. I was permitted to ask the kinds of questions that had been bothering me about education, children, thinking and learning. At times it was slightly daunting to realise anew that I was having these discussions with someone of John White’s stature and experience, but it was a privilege to undertake my studies with him. When he retired I worked additionally with Professor Harry Brighouse and it was remarkable to experience them both discussing my ideas. Since then I have worked with John White through the Philosophy of Education Society of Great Britain for more than a decade and I remain impressed with his energy, breadth of interests, output and convictions. It has been an honour to work on this collection.
