 Some of this rhetoric has survived to the present day, especially among theoretical physicists and cosmologists such as Einstein and  Hawking.[9]  Yet there are clear dangers with relying on a theological justification of simplicity principles. Firstly, many—probably most—contemporary scientists are reluctant to link methodological principles to religious belief in this way. Secondly, even those scientists who do talk of ‘God’ often turn out to be using the term metaphorically, and not necessarily as referring to the personal and intentional Being of monotheistic religions. Thirdly, even if there is a tendency to justify simplicity principles via some literal belief in the existence of God, such justification is only rational to the extent that rational arguments can be given for the existence of  God.[10]
