probabilism

in casuistry, a principle of action grounded on the premise that, when one does not know whether an action would be sinful or permissible, he may rely on a "probable opinion" for its permissibility even though a more probable opinion calls it sinful. An opinion is considered probable either if sound, logical arguments can be cited in its favour (intrinsic probability) or if recognized authorities give it support (extrinsic probability).
