"The heart has its reasons the mind will never know" ...Blaise Pascal In this oft-quoted remark, Pascal was not referring to feelings or hunches, but to our intuitions of self-evidency such as those we have for "the first principles of number, time, space and motion." He follows this with the startling comment that religious truth is known in the same way: "Those to whom God has imparted religion by intuition are very fortunate and justly convinced." Knowing with the Heart analyzes various types of religious experience to see if there are any that can bear the freight of Pascal's suggestion. It defends the view that there are in fact experiences which not only generate belief in God but justify it in the same way that self-evidency intuitions justify scientific principles. Along the way the book offers a criterion for religious belief, a basis for comparing world religions, and replies to some of the most common objections to belief in God. The book is written in clear, nontechnical language and requires no scientific or philosophical background. It is directed to believers concerned with the credentials of their faith and to nonbelievers who are open to investigating those credentials.
