In 1935, Felix Cohen argued in these pages that the technical terminology o
f the law was mere "word-jugglery," and that its practitioners were allowin
g "transcendental nonsense" to stand in for the hard work of functional dec
isionmaking in the law. Professor Waldron argues that in fact technical leg
al vocabulary performs an important function: It flags the systematicity of
the law, highlighting the interrelatedness of diverse concepts and doctrin
es. Cohen, like later legal postivists, largely denied the importance of su
ch systematicity, if he acknowledged it at all. But Professor Waldron sugge
sts that valuing such systematicity, and the technical vocabulary that supp
orts it, is quite compatible with Cohen's functionalist critique of formali
st jurisprudence. In particular, Professor Waldron argues that the role of
technical terms in regard to systematicity is critical for the coherence of
modern legal systems, which develop in a context of pervasive moral disagr
eement and shifting political power.
