is overwhelming
evidence of it."

"Well, then, in the process of evolution, which was evolved first, the
brain, or the mind which operates it and through it?" she asked.

"Why," he replied meditatively, "it is quite likely that they evolved
simultaneously, the brain being the mind's organ of expression."

"But don't you see, Doctor, that you are now making the mind really
come first? For that which expresses a thing is always secondary to
the thing expressed."

"Well, perhaps so," he said. "At any rate, it is quite immaterial to a
practical knowledge of how to meet the brain's ills. I am a practical
man, you know."

"I'm sorry to hear that," she said simply. "Practical men are so
stupid and ignorant."

"Well, I declare!" he exclaimed, putting his hands on his hips and
staring down at the smiling face.

"And you are so nice and friendly, I wouldn't want to think you stupid
and ignorant," she went on blandly.

"H'm! Well, that kind o' takes the edge off your former classification
of me," he said, greatly amused, yet wondering just what appraisal to
place upon this frank girl.

"And evolution," she continued, "is an unfolding, isn't it? You see,
the great fact of creation is the creator, infinite mind. Well, that
mind expresses itself in its ideas. And these it is unfolding all the
time. Now a fact always gives rise to a suppositional opposite. The
opposite of a fact is an error. And that is why error has been called
'negative truth.' Of course, there isn't any such thing as negative
truth! And so all error is simply falsity, supposition, without real
existence. Do you see?"

He did not reply. But she went on unperturbed. "Now, the human, or
carnal, mind is the negative truth of the real mind, God. It is
infinite mind's suppositional opposite. And it imitates the
infinite mind, but in a very stupid, blundering way. And so the whole
physical universe manifests evolution, too--an unfolding, or
revealing, of material types, or mental concepts. And all these
manifest the human mind's sense of life, and its equally strong
sense of death. The universe, animals, men, are all human types,
evolved, or unfolded, or revealed, in the human mind. And all are
the human mind's interpretations of infinite mind's real and eternal
and perfect ideas. You see that, don't you?

"You know," she laughed, "speaking of 'negative truth', the first
chapter of Genesis sets forth positive truth, and the second chapter
sets forth its o
