" The study of Dr. Livingstone would not be complete if we did not take the religious side of his character into consideration. His religion is not of the theoretical kind, but it is a constant, earnest, sincere practice. It is neither demonstrative nor loud, but manifests itself in a quiet, practical way, and is always at work. It is not aggressive, which sometimes is troublesome, if not impertinent. "

― Henry M. Stanley , How I Found Livingstone in Central Africa
