Methodological naturalism – that is, the assumption, for the ends of scientific investigation, that explanations of physical phenomena are only acceptable when they postulate ‘natural’ causes – is a generally accepted element of the scientific method. There is, of course, no particular requirement that a scientific theory should not have recourse to ‘supernatural’ evidence; even so, the criteria of observation, prediction, and experimentation leading to reproducible results are not congenial to the introduction of such evidence. Indeed, the very success of the scientific method, and the concomitant paucity of evidence for any supernatural phenomena, is seen by some as providing strong evidence for metaphysical naturalism – the thesis that the arrangement of matter and energy in spacetime exhausts ‘what there is’.
