4. Radicalism of forms. If a new model once created meets with much success on account of its greater efficiency than its predecessor, it lends certain neighbouring forms a formal radicalism, which attempts to borrow from the appearance of the new form: for example, bronze tools that had reached the furthest development of their utility had a disastrous influence on stone tools, warping them toward an elegance that could only be attained in bronze. Today aviation has imposed its aerodynamic forms even on baby strollers and irons. This radicalism of forms is a result of the fact that people become bored when they do not find some unexpected element in the familiar. This radicalism might seem illogical, as the advocates of standardization believe, but we must not forget that discovery is only made possible by this need of humanity.
