konditionaarisuus

Konditionaarisuus, also known as conditionalism, is a philosophical position that holds that the truth of a proposition is dependent on certain conditions. This view is often associated with the work of philosophers such as David Lewis and Robert Stalnaker, who developed the possible worlds semantics to explain conditional statements. According to konditionaarisuus, the truth of a conditional statement "If P, then Q" is determined by the truth of Q in the closest possible world where P is true. This approach allows for the possibility of counterfactual statements, which are statements about what would be the case if certain conditions were different from what they actually are. For example, the statement "If it had rained yesterday, the ground would be wet" is true according to konditionaarisuus, because in the closest possible world where it rained yesterday, the ground would indeed be wet. However, konditionaarisuus faces challenges in dealing with certain types of conditionals, such as those involving moral or deontic concepts, and in providing a clear criterion for what constitutes the closest possible world. Despite these challenges, konditionaarisuus remains an influential and widely discussed position in contemporary philosophy.
