What did he fear?
The committal of homicide or suicide during sleep by an aberration of the light of reason, the incommensurable categorical intelligence situated in the cerebral convolutions.

Of some one sole unique advertisement to cause passers to stop in wonder, a poster novelty, with all extraneous accretions excluded, reduced to its simplest and most efficient terms not exceeding the span of casual vision and congruous with the velocity of modern life." (U17.1763)
