Appendix I. Faith and Knowledge

Physicists imagine the red of a rose can be traced to oscillation, to variations in wavelength. People say there is really no sound, only vibrations of air. They claim what we hear as sound exists only in our ears. Well, a simple experiment can teach us otherwise, namely, if we have someone wake us up by knocking on the door. We will notice that we were not conscious during the night when we were asleep, but that on waking up we were already living in the knocking. We ourselves have to enter into the knocking sound. We use the other person to do the knocking because our soul itself cannot do it. If we resolved firmly to wake up, we could do so, but this way we are only using the other person as a tool.
