Asymmetry as a challenge to counterfactual accounts of non-causal explanation

This paper examines some recent attempts that use counterfactuals to understand the asymmetry of non-causal scientific explanations. These attempts recognize that even when there is explanatory asymmetry, there may be symmetry in counterfactual dependence. Therefore, something more than mere counterfactual dependence is needed to account for explanatory asymmetry. Whether that further ingredient, even if applicable to causal explanation, can fit non-causal explanation is the challenge that explanatory asymmetry poses for counterfactual accounts of non-causal explanation. This paper argues that several recent accounts (Woodward, in: Reutlinger and Saatsi (eds) Explanation beyond causation: philosophical perspectives on non-causal explanations, Oxford University Press, Oxford, pp 117-140, 2018; Jansson and Saatsi in Br J Philos Sci, forthcoming; Jansson in J Philos 112:7-599, 2015; Saatsi and Pexton in Philos Sci 80: 613-624, 2013; French and Saatsi, in: Reutlinger and Saatsi (eds) Explanation beyond causation: philosophical perspectives on non-causal explanations, Oxford University Press, Oxford, pp 185-205, 2018) fail to meet this challenge. The paper then sketches a more positive proposal for dealing with explanatory asymmetry in non-causal explanations.
