 To sum up, rule of thumb moral particularism makes room for a posteriori moral knowledge and a posteriori moral justification. Although it leaves open the possibility that some moral knowledge and justification is a priori (in the way Dancy describes), it denies that all moral knowledge/justification is a priori; rule of thumb particularists hold that one can justifiably infer at least some moral conclusions from experience, testimony, and (experience-supported) beliefs about the kinds of contexts one is likely to encounter.
