“If I flipped a coin, it would fall on heads or on tails”: this is a true counterfactual statement. But I cannot say that my act causes the coin to fall on heads, nor that it causes the coin to fall on tails. And yet, my act erases a number of alternatives; for example, it ensures that the coin does not stay in my pocket. In this weak sense, coin-tossing is a cause of the state of the coin; an indeterministic cause of it. The most common approach to the study of causation, structural equation modeling, represents causal laws as functional, deterministic laws. In this project, I will use a novel semantic framework (causal team semantics) to challenge this tenet of causal modelling; I will show how this framework can model the interplay of causation and indeterminism, and I will systematically study the logical laws that govern the causal counterfactuals when determinism is abandoned.
