 In spelling out their position the empiricists distinguished between two styles of inference. What they rejected was the variety of reasoning they called “analogism” (analogismos), which “starts from what is apparent but ends up with what is entirely unclear” (Galen SB ch. 5). In its place they advocated what they called “epilogism” (epilogimos), which deals “solely with what is apparent,” but can be used “to discover what is currently unseen” (Galen SB ch. 5). The idea here is that while the cause that is inferred may be currently hidden, the inference is based on an association that is, at other times, directly observable. Epilogismos, the empiricists argued, is a form of reasoning used by all human beings, which leads to a consensus, while analogismos leads to disagreement and conclusions that can be neither confirmed nor denied (Galen ME ch. 24).
