The National Secular Society's criticism of Aberdeen University for establishing a Centre for the Study of Spirituality, Health and Disability ("Row over 'pseudo science'", February 6) seems based on a belief that it is the object of scientific inquiry, here spirituality, rather than the rigour and validity of the research method that determines if the science is real or "pseudo".

But it is entirely possible to conduct a rigorous and valid scientific investigation into spirituality and health. Attempts to put some areas of human experience off limits erode the quest for understanding that drives real science. Whether or not the centre produces real science will be decided by peer review.
