One of the six moral foundations. Sanctity, or purity, is defined as abhorrence for disgusting things, foods, actions; opposite of degradation
This foundation was shaped by the psychology of disgust and contamination. It underlies religious notions of striving to live in an elevated, less carnal, more noble way. It underlies the widespread idea that the body is a temple which can be desecrated by immoral activities and contaminants (an idea not unique to religious traditions).
