The empiricists make a good point:
"Haught then attempts to establish that religious experience – the felt presence of God – is trustworthy evidence of God’s reality"The problem with "religious" experience is that there is no way of determining what is true or false. Mormons feel a burning of the bosom; I've talked with Adventists who feel peace, having accepted the Sabbath into their hearts (not those exact words, but similar). Even Muslims can cite miraculous experiences relating to the Koran. Similarly, I have my own experiences I can point to.
Experience is not definitive, but it can be instructive. Indeed, what are scientific results, but experiential (I witnessed these measurements on these devices).
So experience must be accounted for, but it does not have ultimate authority. Authority lies elsewhere, as we shall see (soon).
Also, many "religious" practices shut off the brain. The Bible has nothing good to say about these practices.
