JOHN Stuart Mill was among the foremost liberal thinkers of modern times who wrote extensively on economics and philosophy. Though under the influence of his wife Harriet Taylor Mill, he came closer towards socialism late in his life, it was a kind of cooperative socialism that attracted him; he continues to be regarded primarily as a pre-eminent liberal thinker. Economists of Mill’s time were haunted by the fear of the imminence of a stationary state, that is, a state of simple reproduction or zero growth-rate, in which there would be no further capital accumulation.
