The princicples of modularity, simplicity, or orthogonality, insofar as they contribute to overall simplicity, are an excellent means to an end; but as a substitute for simplicity they are very questionable. Since in practice they have proved to be a technically more difficult achievement than simplicity, it is foolish to accept them as primary objectives.
