Книжка по теме эпистемологии религиозного опыта. В своё время отыграла определённую роль в дискуссиях по данной теме. Вот как Куань Кхаймань это комментирует:
One landmark of this debate is William Alston's Perceiving God which was published in 1991.[15] In this book, Alston brought his analytical skills to the issue of religious experience and defended a doxastic practice approach to epistemology. This approach said that it was practically rational to trust our socially established doxastic practices, including the Christian Mystical Practice. His arguments were discussed in major analytic philosophy journals, e.g. Nous, The Journal of Philosophy. Both Philosophy and Phenomenological Research and Religious Studies have organized symposia to discuss his book in 1994.[16]
