In recent years, the debate over science, reason, and religion has reached a peak (or a high plateau, depending on your perception of time scales) of intensity, breadth, and confrontational vigor. Hundreds of Web sites, blogs, and forums have sprung up, enabling the debate to rage day-to-day. But people will always want points of view to be encapsulated in portable form: books.

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.
