Faith in the Unseen is a contribution to the debate. Its author, Dr. Rashid Seyal, who is a consultant cardiologist with numerous books on cardiology and religion under his belt, approaches the debate on the "faith" side as a religious man (he is a Muslim) with a strong background in science. The title of his book places the emphasis on the key issue that stands between the scientific atheist side and the faith side: evidence, and the absence thereof. For fundamentalist believers, evidence (other than what is written in holy books) is simply not an issue. However, for the rational religious believer, it is a pivotal point and must be rationalized.
It is divided into substantial chapters, each dealing with a major subject of faith and/or reason, and each chapter is subdivided into sections, which discuss various detailed aspects or examples, including death, the afterlife, and the philosophy of life.
