Logic of Desires Emiliano Lorini University Paul Sabatier, IRIT-CNRS, LILaC team, Toulouse, France An important and general distinction in philosophy of mind is between epistemic attitudes and motivational attitudes.
This distinction is in terms of the direction of fit of mental attitudes to the world.
While epistemic attitudes aim at being true and their being true is their fitting the world, motivational
attitudes aim at realization and their realization is the world fitting them.
The philosopher John Searle calls “mind-to-world” the first kind of direction of fit and “world- to-mind” the second one.
There are different kinds of epistemic and motivational attitudes with different functions and properties.
Examples of epistemic attitudes are beliefs, knowledge and opinions, while examples of motivational attitudes are desires, preferences, moral values and intentions.
The course is aimed at discussing logics for modeling static and dynamic aspects of motivational attitudes
whose most representative example is the logic of desires.
The first session of the tutorial will devoted to discuss the logic
of desires in opposition to the logics of knowledge and belief
(epistemic logic and doxastic logic) The second session of the tutorial will be devoted to the problems of preference generation and intention formation: (i) how preferences of agents are determined both by her desires and by her moral values, and (ii) how beliefs and preferences determine choices and are responsible for the formation of new intentions about present actions (present-directed intentions) and future actions (future- directed intentions). The third session will be devoted to the dynamic aspects of desires including desire expansion and desire revision as well as the connection between desire and belief change, on the one hand, and preference change on the other hand. |
