Tanzania society is very religious. This is the conclusion reached in this ground breaking book on the religious landscape of Tanzania. Religious institutions play a dominant role in the lives of millions of Tanzania’s. Not only do they offer spiritual guidance, but they also play a critical role in the provision of social services. But useful and seemingly even powerful as they are, religions are also inherently potentially divisive phenomena. Because theism, in particular, involves the deification of an external metaphysical object, it easily leads to the assertion that “my god is better than yours,” and that “my way of worship is superior to yours.” The book exposes several interesting findings. One of these is the size of the Tanzanian population who still subscribe to the indigenous belief systems; another is the extent to which these system still color the practices of confessed Muslims and Christians; a third is that, while Tanzania has been basking in relative freedom from religious strife, events in the last two decades warm that this should not be taken for grated. So far, the conflicts within the two major religions present greater cause for concern than those between them. But if the relationships between and within religions are generically potentially conflictual, the one between religion and politics is even more so.
