I don't get it, why is it so important to separate our cognitive system into infinite units, one for everything we can feel?
Why can't we, as an alternative, not possess two believes at the same time? Composed by different parts of the cognitive system. One for example might go through the frontal lobe and be overwritten by "reason" (if there is such a thing), and the other might go through more rostral regions, and be overwritten by emotions (which, in fact, will manifest it self into muscle movments)?
Another alternative might be that the same stimuli manifests it self in different ways at the same time, after going through different coginitive systems (no a/believe construct required). So the fearfull ("irrational") behaviour ("the alive") gets manifested in the sympathetic nervous system (into muscle movements, hormonse, thermo-regualtion),while the vocal ("rational") behaviour ("the believe") gets manifested in cognitive systems responsable for speach-like cognitions, i.e. frontal regions.

It isn't. It depends entirely on the specific school of psychology. For example the school of Behaviorism states that only observable behavior matters; cognitive stuff like this is unimportant.
