However, canons seem to have a disturbing aspect. By operating with a dialectic of inclusions and exclusions, they seem to presuppose a kind of authority that decides what comes in and what stays out. That has always been a sufficient reason why canons are often encountered with mistrust. However, this mistrust is based on the popular fallacy that canons are static and homogenous, a notion which fails to do justice to both their inherent dynamic and striking variety.

The dialectics of inclusion and exclusion bring to light what is perhaps the most beneficiary effect of canons: their enormous ability to generate profound questions and instigate discussions of crucial issues. However suggestive of authorities canons may seem, through their dialectic movement, they rather challenge them. Because their open character invites us to reflect about what is of importance to us and not to submissively accept what is considered crucial by a tradition, which is also itself a system of canons.
