Originally published in 1922. The author's experiences as a doctor/explorer in the untamed forests of Equatorial Africa.I had read about the physical miseries of the natives in the virgin forests; I had heard about them from missionaries, and the more I thought about it the stranger it seemed to me that we Europeans trouble ourselves so little about the great humanitarian task which offers itself to us in far-off lands. The parable of Dives and Lazarus seemed to me to have been spoken directly of us! We are Dives, for, through the advances of medical science, we now know a great deal about disease and pain, and have innumerable means of fighting them: yet we take as a matter of course the incalculable advantages which this new wealth gives us! Out there in the colonies, however, sits wretched Lazarus, the coloured folk, who suffers from illness and pain just as much as we do, nay, much more, and has absolutely no means of fighting them. And just as Dives sinned against the poor man at his gate because for want of thought he never put himself in his place and let his heart and conscience tell him what he ought to do, so do we sin against the poor man at our gate.
