Quoting Dr. Penfield, “Throughout my own scientific career I, like other scientists, have struggled to prove that the brain accounts for the mind. But now, perhaps, the time has come when we may profitably consider the evidence as it stands, and ask the question: Do brain-mechanisms account for the mind? Can the mind be explained by what is now known about the brain? If not, which is the more reasonable of the two possible hypotheses: that man’s being is based on one element, or on two? . . . But it is, I believe, a mystery that science will solve some day. In that day of understanding, I predict that true prophets will rejoice, for they will discover in the scientist a long-awaited ally in the search for Truth.
