Once, when a religionist denounced me in unmeasured terms, I sent him a card saying, "I am sure you believe that I will go to hell when I die, and that once there I will suffer all the pains and tortures the sadistic ingenuity of your deity can devise and that this torture will continue forever. Isn't that enough for you? Do you have to call me bad names in addition?
To be able to listen -- really, wholly passively, self-effacingly listen -- without presupposing, classifying, improving, controverting, evaluating, approving or disapproving, without dueling with what is being said, without rehearsing the rebuttal in advance, without free-associating to portions of what is being said so that succeeding portions are not heard at all -- such listening is rare.
