Abstract

The most recent challenge to the covering-law model of explanation (N. Cartwright, How the laws of Physics Lie) charges that the fundamental explanatory laws are not true. In fact explanation and truth are alleged to pull in different directions. We hold that this gets its force from confusing issues about the truth of the laws in the explanation and the precision with which those laws can yield an exact description of the event to be explained. In defending this we look at Cartwright's major case studies and sketch an amended covering-law model of explanation.
