Contrary-to-Duty Obligations

We investigate under what conditions contrary-to-duty (CTD) structures lacking temporal and action elements can be given a coherent reading. We argue, contrary to some recent proposals, that CTD is not an instance of defeasible reasoning, and that methods of nonmonotonic logics are inadequate since they are unable to distinguish between defeasibility and violation of primary obligations. We pro...

Detection of contrary chromatic change.

In visual search experiments we examined whether targets that are distinguished from distracting items solely by a contrary change in color can be sought spatially in parallel. Targets under time-varying illumination pop out if they present a contrary luminance signal; targets under space-varying illumination can be detected in parallel when they are isoluminant. The results suggest that neuron...

Expressivism and Contrary-forming Negation

The task is to make sense of logically complex sentences like 'If I insulted the host then I ought to apologize', to do so by making sense of the states of mind such sentences would be used to express, and to preserve the validity of intuitively valid...
