Sir, - Congratulations on your timely, eloquent and well-informed obituary of Willard Quine (The Irish Times, January 6th). It's heartening that you find the time and space to take note of the departure from this world of one of the leading philosophers of our time. - Yours, etc.,
Dr Harry McCauley, Faculty of Philosophy, National University of Ireland, Maynooth, Co Kildare.
