A dialogue is very important. It is a form of communication in which question and answer continue till a question is left without an answer. Thus the question is suspended between the two persons involved in this answer and question. It is like a bud with untouched blossoms . . . If the question is left totally untouched by thought, it then has its own answer because the questioner and answerer, as persons, have disappeared. This is a form of dialogue in which investigation reaches a certain point of intensity and depth, which then has a quality that thought can never reach.
