It must not be inferred that either Warren Proudhon or Marx used exactly this phraseology or followed exactly this line of thought but it indicates definitely enough the fundamental ground taken by all three and their substantial thought up to the limit to which they went in common. And lest I may be accused of stating the positions and arguments of these men incorrectly it may be well to say in advance that I have viewed them broadly and that for the purpose of sharp vivid and emphatic comparison and contrast I have taken considerable liberty with their thought by rearranging it in an order and often in a phraseology of my own but I am satisfied without in so doing misrepresenting them in any essential particular.
