– We introduce a model of interacting Brownian particles in a symmetric, periodic potential that undergoes a noise-induced non-equilibrium phase transition. The associated spontaneous symmetry breaking entails a ratchet-like transport mechanism. In response to an external force we identify several novel features; among the most prominent being a zero-bias negative conductance and a prima facie ...

In a rejoinder to Rakos (1989), I discuss three inter-related problems: scientifically inappropriate reductionism, a culturally biased concept of human nature, and a bourgeois view of capitalism and socialism. I argue that these three problems result from the Cartesian (positivistic) world outlook in which the part is held to be ontologically prior to the whole, a pervasive philosophical perspe...
