Abstract
We develop a nonlinear generalization of the causal linear thermodynamics of bulk viscosity, incorporating
the positivity of the entropy production rate and the effective specific entropy. The theory is applied to viscous
fluid inflation ~which is necessarily far from equilibrium!, and we find thermodynamically consistent inflationary
solutions, both exponential and power law.
