Galen also claims to have had personal experience of interventions by individual gods of the Greek polytheistic world within human affairs, most notably by Asclepius, the god of medicine (see Pietrobelli 2013; Singer 2019a). If it seems difficult to reconcile such a conventional, anthropomorphic manifestation of religion with the philosophical view of God as a teleological cause or as immanent Nature, it should perhaps be said that such a co-existence of abstract theology with traditional individual gods is by no means confined to Galen, amongst Graeco-Roman philosophical writers (one could mention both Plato and Epictetus in this context). In any case, it is to the divine intelligence manifest throughout the universe, rather than to any individual god, that Galen constantly returns; it is this intelligence which is the object of his religious—and by the same token of his intellectual, indeed his scientific—fervour.
