One should not wrongly reify 'cause' and 'effect,' as the natural scientists do (and whoever, like them, now 'naturalizes' in his thinking), according to the prevailing mechanical doltishness which makes the cause press and push until it 'effects' its end; one should use 'cause' and 'effect' only as pure concepts, that is to say, as conventional fictions for the purpose of designation and communication-not for explanation.
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.
letters are venerable; and the telephone valiant, for the journey is a lonely one, and if bound together by notes and telephones we went in company, perhaps - who knows? - we might talk by the way.
