One can think of possible answers to this question as falling along a con¬tinuum. On one extreme is the contractarian answer: Producers owe only those things promised to consumers in the sales agreement. At the other extreme is something closer to strict liability: Producers owe compensation to consum¬ers for any harms caused by their products. In between these extremes is a range of answers that vary with different interpretations of negligence. We have already suggested why the strict contractarian approach is not convinc¬ing. In the next section we shall examine the pros and cons of strict products liability. The remainder of this section will examine the important concept of negligence.
