You see, we have made of truth something permanent. And is truth permanent? If it is, then it is within the field of time. To say that something is permanent implies that it is continuous; and what is continuous is not truth. That is the beauty of truth: it must be discovered from moment to moment, not remembered. A remembered truth is a dead thing. Truth must be discovered from moment to moment because it is living, it is never the same; and yet each time you discover it, it is the same. What is important is not to make a theory of truth, not to say that truth is permanent in us and all the rest of it - that is an invention of the old who are frightened both of death and of life. These marvellous theories - that truth is permanent, that you need not be afraid because you are an immortal soul, and so on - have been invented by frightened people whose minds are decaying and whose philosophies have no validity. The fact is that truth is life, and life has no permanency. Life has to be discovered from moment to moment, from day to day; it has to be discovered, it cannot be taken for granted. If you take it for granted that you know life, you are not living. Three meals a day, clothing, shelter, sex, your job, your amusement and your thinking process - that dull, repetitive process is not life. Life is something to be discovered; and you cannot discover it if you have not lost, if you have not put aside the things that you have found. Do experiment with what I am saying. Put aside your philosophies, your religions, your customs, your racial taboos and all the rest of it, for they are not life. If you are caught in those things you will never discover life; and the function of education, surely, is to help you to discover life all the time. A man who says he knows is already dead. But the man who thinks, "I don't know", who is discovering, finding out, who is not seeking an end, not thinking in terms of arriving or becoming - such a man is living, and that living is truth.
