ISBN 978-1285055350.«Socialist writers of the nineteenth century proposed socialist arrangements for sharing as a response to the inequality and poverty of the industrial revolution. English socialist Robert Owen proposed that ownership and production take place in cooperatives, where all members shared equally. French socialist Henri Saint-Simon proposed to the contrary: socialism meant solving economic problems by means of state administration and planning, and taking advantage of new advances in science.»
