Common Sense Voices I claim that one cannot enter, for the first time, into the territory of some domains of knowledge while listening to common sense voices. Our common sense will immediately reject some facts because those facts are contrary to common sense. You must still these instinctive reactions because common sense knows nothing about many things. The physicist must still her common sense reaction at the results of some experiments regarding the inner working of the atom. The inner working of human nature can be as mysterious to common sense as is the inner reality of the atom. We can see only what we are prepared to see. Common sense does not prepare us to see many things. We have to creep up on certain matters and withhold judgment until we are intellectually sophisticated enough to judge their reality.
