“…An initial interpretation of a counterfactual premise might follow the particular constraints of the conceptual combination that is required (e.g., ''If blood contained chlorophyll''; see Costello & Keane, 2000;Springer & Murphy, 1992; for accounts in terms of conceptual blending, see Coulson, 2001;Coulson & Fauconnier, 1999;Coulson & Oakley, 2005). Readers might not consider information that undermines coherency of the counterfactual world (e.g., that high levels of chlorophyll in blood are potentially deadly to animals and humans, and that blood would not be blood if it contained mostly chlorophyll, see Murphy & Medin, 1985), as part of the 'suspension of disbelief' required for such sentences (e.g., Searle, 1975).…”
