As I continue reading "The End of Faith" I came across a section that shows that author Sam Harris does see the value of spiritual experience, in the way he defines it. He is not one of those cynics who can do nothing more than gripe about dogma.
I thought I'd present a passage that impressed me last night:
___________
The World beyond Reason
As we will see in the last chapter of this book, there is little doubt that a certain range of human experience can be appropriately described as "spiritual" or "mystical" --experiences of meaningfulness, selflessness, and heightened emotion that surpass our narrow identities as "selves" and escape our current understanding of the mind and brain. But nothing about these experiences justifies arrogant and exclusionary claims about the unique sanctity of any text. There is no reason that our ability to sustain ourselves emotionally and spiritually cannot evolve with technology, politics, and the rest of culture. Indeed, it must evolve, if we are to have any future at all.
The basis of our spirituality surely consists in this: the range of possible human experience far exceeds the ordinary limits of our subjectivity. Clearly, some experiences can utterly transform a person's vision of the world. Every spiritual tradition rests on the insight that how we use our attention, from moment to moment, largely determines the quality of our lives. Many of the results of spiritual practice are genuinely desirable, and we owe it to ourselves to seek them out. It is important to note that these changes are not merely emotional but cognitive and conceptual as well. Just as it is possible for us to have insights in fields like mathematics or biology, it is possible for us to have insights about the very nature of our own subjectivity. A variety of techniques, ranging from the practice of meditation to the use of psychedelic drugs, attest to the scope of plasticity of human experience. For millennia, contemplatives have known that ordinary people can divest themselves of the feeling that they call "I" and thereby relinquish the sense that they are separate from the rest of the universe. This phenomenon, which as been reported by practitioners in many spiritual traditions, is supported by a wealth of evidence --neuroscientific, philosophical, and introspective. Such experiences are "spiritual" or "mystical," for want of better words, in that they are relatively rare (unnecessarily so), significant (in that they uncover genuine facts about the world), and personally transformative. They also reveal a far deeper connection between ourselves and the rest of the universe than is suggested by the ordinary confines of our subjectivity. There is no doubt that experiences of this sort are worth seeking, just as there is no doubt that the popular religious ideas that have grown up around them, especially in the West, are as dangerous as they are incredible. A truly rational approach to this dimension of our lives would allow us to explore the heights of our subjectivity with an open mind, while shedding the provincialism and dogmatism of our religious traditions in favor of free and rigorous inquiry.
