Knowledge is necessary to act in the sense of my going home from here to the place I live; I must have knowledge for this; I must have knowledge to speak English; I must have knowledge to write a letter and so on. Knowledge as function, mechanical function, is necessary. Now if I use that knowledge in my relationship with you, another human being, I am bringing about a barrier, a division between you and me, namely the observer. That is, knowledge, in relationship, in human relationship, is destructive. That is knowledge which is the tradition, the memory, the image, which the mind has built about you, that knowledge is separative and therefore creates conflict in our relationship.
