Marx and Engels once thought the contrast between the essence and appearance of things was the source of "all" science. Whether it is a "contrast" relation or not, the desire to understand and, hence, categorize (i.e., find equivalence classes) the profound relation between form and function is what keeps my mind busy recently. Right, it is not surprising that the these two men also looked at the equivalence classes in their subject of interest. Did you also know that the famous Brazilian educator P. Freire once said "If I had ever wanted to be a toolsmith I would have stayed in my village"?
