  We present an approach to the computation of the non-Abelian statistics of
quasiholes in quantum Hall states, such as the Pfaffian state, whose
wavefunctions are related to the conformal blocks of minimal model conformal
field theories. We use the Coulomb gas construction of these conformal field
theories to formulate a plasma analogy for the quantum Hall states. A number of
properties of the Pfaffian state follow immediately, including the Berry phases
which demonstrate the quasiholes' fractional charge, the abelian statistics of
the two-quasihole state, and equal-time ground state correlation functions. The
non-Abelian statistics of multi-quasihole states follows from an additional
assumption.
