West African Shamanism 

In my study of the natives' language my attention was drawn closely to their customs; and in my inquiry into their religion I at once saw how it was bound up in these customs. I met with other white men-traders, government officials, and even some missionaries-whose interest in Africa, however deep, was circumscribed by their special work for, respectively, wealth, power, and Gospel proclamation. They could see in those customs only "folly,"and in the religion only "superstition."
I read many books on other parts of Africa, in which the same customs and religion prevailed. I did not think it reasonable to dismiss curtly as absurd the cherished sentiments of so large a portion of the human race. I asked myself: Is there no logical ground for the existence of these sentiments, no philosophy behind all these beliefs? I began to search; and thenceforward for thirty years, wherever I travelled, wherever I was guest to native chief, wherever I lived, I was always leading the conversation, in hut or camp, back to a study of the native thought.
I soon found that I gained nothing if I put my questions suddenly or without mask. The natives generally were aware that white men despised them and their beliefs, and they were slow to admit me to their thought if I made a direct advance. But, by chatting as a friend, telling them the strange and great things of my own country, and first eliciting their trust in me and interest in my stories, they forgot their reticence, and responded by telling me of their country. I listened, not critically, but apparently as a believer; and then they vied with each other in telling me all they knew and thought.
