Hume's doctrine of natural belief allows that certain beliefs are justifiably held by all men without regard to the quality of the evidence which may be produced in their favour. Examples are belief in an external world and belief in the veracity of our senses. According to R. J. Butler, Hume argues in the Dialogues that belief in God is of this sort. More recently John Hick has argued that for some people it is as natural to believe in God (...) as to believe in an external world. I shall first inquire what Hume understands by reasonable belief and by natural belief. I shall then use the results of this investigation to argue, against Butler, that belief in God is not a natural belief; and against Hick, more briefly, that his thesis is not viable in as far as it depends upon Hume's doctrine of natural belief. These discussions are important to the philosophy of religion since by means of natural beliefs it could be urged that belief in God is something justifiable without reference to reason or evidence: a position which would be of immense value to the theist.
