"Painting has to extract the Figure from the figurative. But Bacon invokes two developments which seem to indicate that modern painting has a different relation to figuration or illustration than the painting of the past has. First, photography has taken over the illustrative and documentary role, so that modern painting no longer needs to fulfill this function, which still burdened earlier painters. Second, painting used to be conditioned by certain 'religious possibilities' that still gave a pictorial meaning to figuration, whereas modern painting is an atheistic game.
Yet it is by no means certain that these two ideas, taken from Malraux, are adequate. On the one hand, such activities are in competition with each other, and one art would never be content to assume a role abandoned by another. It is hard to imagine an activity that would take over a function relinquished by a superior art. The photograph, though instantaneous, has a completely different ambition than representing, illustrating, or narrating. And when Bacon speaks of his own use of photographs, and of the relationships between photography and painting, he has much more profound things to say. On the other hand, the link between the pictorial element and religious sentiment, in past painting, in turn seems poorly defined by the hypothesis of a figurative function that was simply sanctified by faith."
