“If we assume that the person asking the question is serious, there is an underlying background of purposes and understanding (the 'horizon' as Gadamer calls it) into which the question fits. If a questioner were to ask "Can pigs have wings?" a respondent within the analytic tradition might have difficulty answering, because although the idea is outrageously farfetched, current work in genetic engineering does leave open the logical possibility of creating a beast with the desired characteristics. Admittedly, there might be some refuge in challenging the asker as to whether such a monstrosity would still properly be called a pig,11 thereby invalidating the question. But if the question were asked seriously, neither the logical possibility nor the precise meaning of "pig" would be the issue at hand. The questioner would be asking for some reason in some background of understanding and purpose, and the appropriate answer (just like the appropriate answer to "Is there water in the refrigerator?") would have to be relevant to that background.”

Context: Euclid... gave his famous definition of a point: "A point is that which has no parts, or which has no magnitude." …A point has no existence by itself. It exists only as a part of the pattern of relationships which constitute the geometry of Euclid. This is what one means when one says that a point is a mathematical abstraction. The question, What is a point? has no satisfactory answer. Euclid's definition certainly does not answer it. The right way to ask the question is: How does the concept of a point fit into the logical structure of Euclid's geometry?... It cannot be answered by a definition.

Context: In regard, then, to the sacred tradition of humanity, we learn that it consists, not in propositions or statements which are to be accepted and believed on the authority of the tradition, but in questions rightly asked, in conceptions which enable us to ask further questions, and in methods of answering questions. The value of all these things depends on their being tested day by day. The very sacredness of the precious deposit imposes upon us the duty and the responsibility of testing it, of purifying and enlarging it to the utmost of our power. He who makes use of its results to stifle his own doubts, or to hamper the inquiry of others, is guilty of a sacrilege which centuries shall never be able to blot out. When the labours and questionings of honest and brave men shall have built up the fabric of known truth to a glory which we in this generation can neither hope for nor imagine, in that pure and holy temple he shall have no part nor lot, but his name and his works shall be cast out into the darkness of oblivion for ever.

Context: Are we wasting our lives? By that word “wasting” we mean dissipating our energy in various ways, dissipating it in specialized professions. Are we wasting our whole existence, our life? If you are rich, you may say, “Yes, I have accumulated a lot of money, it has been a great pleasure.” Or if you have a certain talent, that talent is a danger to a religious life. Talent is a gift, a faculty, an aptitude in a particular direction, which is specialization. Specialization is a fragmentary process. So you must ask yourself whether you are wasting your life. You may be rich, you may have all kinds of faculties, you may be a specialist, a great scientist or a businessman, but at the end of your life has all that been a waste? All the travail, all the sorrow, all the tremendous anxiety, insecurity, the foolish illusions that man has collected, all his gods, all his saints and so on — have all that been a waste? You may have power, position, but at the end of it — what? Please, this is a serious question that you must ask yourself. Another cannot answer this question for you.
