We define a formal semantics of conditionals based on normatively ideal worlds. Such worlds are described informally by Armgardt (Gabbay D, Magnani L, Park W, Pietarinen A-V (eds), Natural arguments: a tribute to John Woods, College Publications, London, pp 699-708, 2018) to address well-known problems of the counterfactual approach to causation. Drawing on Armgardt’s proposal, we use iterated conditionals in order to analyse causal relations in scenarios of multi-agent interaction. This results in a refined counterfactual approach to causal responsibility in legal contexts, which solves overdetermination problems in an intuitively accessible manner.
