The idea of innate and universal facial expressions that have links wi
th human emotions was given the status of scientific hypothesis by Dar
win (1872/1965). Substantial evidence, old and new, supports his hypot
hesis. Much of the evidence is independent of language, but Russell's
(1994) criticisms of the hypothesis focus on language-dependent data.
In this article, iris argued that Russell's critique was off target in
that his arguments relate only to a hypothesis of the universality of
semantic attributions and overstated in that he used questionable log
ic in designing studies to support his claims. It is also argued that
Russell misinterpreted the relation between the universality hypothesi
s and differential emotions theory. Finally, new evidence is presented
that supports the Darwinian hypothesis of the innateness and universa
lity of the facial expressions of a limited set of emotions and the ef
ficacy of the most commonly used method of testing it.
