To this purpose, we extend the notion of a causal model with a representation of the epistemic state of an agent.

The most widespread model for such situations of 'radical uncertainty' is in terms of imprecise probabilities, i. e. representing the agent's knowledge as a set of probability measures.

In our combined setting, we use a topological semantics to represent the structure of an agent's collection of evidence, and we use argumentation theory to single out the relevant sets of evidence through which a notion of beliefs grounded on arguments is defined.

We introduce a theory $\mathsf{JCDL}$ of Justified Conditional Doxastic Logic that replaces conditional belief formulas $B^\psi\varphi$ by expressions $t{\,:^{\psi}}\varphi$ made up of a term $t$ whose syntactic structure suggests a derivation of the belief $\varphi$ after revision by $\psi$.
