"How We Think"
John Dewey
Strong in the abundant but unsifted learning of his day, a style of learning, which in his case was strangely inaccurate, he not only mixed the past with the present, fairyland with politics, mythology with the most serious Christian ideas, but he often mixed together the very features which are most discordant, in the colours, forms, and methods by which he sought to produce the effect of his pictures.
