fundamental dogma of materialism is false.
There are existences which can neither be felt, tasted, nor seen."

"The vivifying principle is also in animals," said Richard.

"Certainly; and in them also intangible and mysterious. Materialism
cannot even stand before animal life; for even there the vivifying
principle is an immaterial existence."

"The materialist stumbles at the existence of human spirit, because he
cannot get a conception of it."

"How could this be possible?" cried the doctor. "The conception is a
picture in the mind, an apprehension of the senses. Spiritual being is
as unapproachable by the senses as the vivifying principle, of which
also man can form no conception. To deny existence because you cannot
have a conception of it, is foolish. The blind would have the same
right to deny the existence of colors, or the deaf that of music. And
who can have a conception of good, of eternity, of justice, of virtue?
No one. These are existences that do not fall under the senses. To be
logical, the materialist must conclude that there is nothing good,
nothing noble, no justice; for we have not yet seen nor felt nor smelt
these things. Virtuous actions we can, of course, see; but these
actions are not the cause but the consequence, not the thing working
but the thing wrought. As these actions will convince every thinking
man of the existence of virtue and justice, so must the workings of the
spirit prove its existence."

"Precisely," replied Frank. "Materialism only surprises and captivates
one like a dream of the night. It vanishes the moment it is seen. I
read the works of Vogt and Buechner only for diversion; my object was
perfectly gained."

"You read for diversion! What did you wish to forget?"

"Dark clouds that lowered over my mind."

"Have you secrets that I, your old friend and well-meaning adviser,
should not know?"

Frank was confused; but his great respect for the doctor forced him to
be candid.

"You know my views of women. When I tell you that Angela, the
well-known Angel of Salingen, has torn these opinions up by the roots,
you will not need further explanation."

"You found Angela what I told you? I am glad," said Klingenberg. And
his disputative countenance changed to a pleasant expression. "I
suspected that the Angel of Salingen made a deep impression on you. I
did not guess; I read it in large characters on your cheeks. Have you
made an avowal?"

"No; it will never come to that.
