              It should be noted that Aristotle’s arguments for the four causes taken individually all proceed against the backdrop of the general connection he forges between causal explanation and knowledge. Because he thinks that the four aitia feature in answers to knowledge-seeking questions (Phys. 194b18; A Po. 71 b 9–11, 94 a 20), some scholars have come to understand them more as becauses than as causes—that is, as explanations rather than as causes narrowly  construed.[18]   Most such judgments reflect an antecedent commitment to one or another view of causation and explanation—that causation relates events rather than propositions; that explanations are inquiry-relative; that causation is extensional and explanation intensional; that explanations must adhere to some manner of nomic-deductive model, whereas causes need not; or that causes must be prior in time to their effects, while explanations, especially intentional explanations, may appeal to states of affairs posterior in time to the actions they explain.
