I think that when Jones wrote “Construction should be decorated. Decoration should never be purposely constructed.” He was saying that it is fine to decorate an object as long as the decorations do not distract it from its original intention, but if an object is more about its decoration than its useful intention it is bad design.
I agree with what Jones has to say. In our modern day when we find something that is more tacky ornament than useful object, it falls into the category of ‘decoration constructed’. For example, this lamp that has a casting of an elk as its base. There is no reason why an elk is or should be associated with giving light, so not only is it ‘decoration constructed but it also has a number of the false principals according to A.W.N Pugin. It imitates nature and it is an inappropriate decoration of function.
