Unity of knowledge is not easily achieved in todayÝs Africa where often there is little conscious interaction between traditional beliefs, Christian faith and modern secularity. The challenge is taken up in this book as scholars from a variety of disciplines wrestle with the relation of faith and science at the frontiers of knowledge. The results are important alike for the integrity of faith, for scienti?c advance and for the attainment of creative cultural unity in society. Readers with such concerns at heart will ?nd much food for thought as they traverse the broad frontiers explored in these wide-ranging essays.
