In his article 'Specifying. balancing and interpreting bioethical principle
s' (Richardson, 2000). Henry Richardson claims that the two dominant theori
es in bioethics - principlism, put forward by Beauchamp and Childress in Pr
inciples of Bioethics, and common morality, put forward by Gert, Culver and
Clouser in Bioethics: A Return to Fundamentals - are deficient because the
y employ balancing rather than specification to resolve disputes between pr
inciples or rules. We show that, contrary to Richardson's claim, the major
problem with principlism, either the original version, or the specified pri
nciplism of Richardson, is that it conceives of morality as being composed
of free-standing principles, lather than as common morality conceives it, a
s being a complete public system, composed of rules. ideals, morally releva
nt features, and a procedure for determining when a rule can be justifiably
violated.
