AB There exists certain circularity between the formation of some epistemic atti-tudes of an agent and the way she assesses her available arguments. For the sake of simplicity,I will restrict my attention to the case of beliefs in what follows. The mentioned circularityarises when one tries to embrace two principles that, taken separately, seems to be intuitivelyacceptable:1. When an agent assesses her available arguments, she should take into account herbeliefs with respect to the premises. In this sense, arguments with believed premisesshould be taken to be stronger by the agent than arguments whose premises are notbelieved.2. The beliefs of an agent should be partially determined by the evaluation she performsof her available arguments. To be more precise, if an agent is considering her doxasticattitude towards a proposition P, then she should  rst assess her available argumentsabout P and form her belief consequently (for instance, by believing P if her strongestargument is in favour of P)The tension between both principles becomes clearer when one compares works in formalargumentation (endorsing the  rst one) to works in epistemic logic (endorsing the secondone). During my talk, I will propose a formal model that allows us to (consistently) endorsesome version of both principles. After that, I will explain that the epistemological view thatunderlies this model corresponds to some sort of foundationalism. In this view of founda-tionalism, we can distinguish between basic beliefs and argument-based beliefs. Within thesecond class, another distinction can be drawn between strong beliefs (based on deductivearguments) and weak beliefs (based on defeasible arguments). To conclude, I will point outwhat kind of epistemic actions can change each type of beliefs.
