 Consider again the choice among alternative architectural designs for a new building. As indicated above, our preferences can be expressed with a vector \(\langle \succcurlyeq_1 ,\ldots ,\succcurlyeq_n \rangle\), each of whose elements represents our partial preferences with respect to some particular aspect such as sustainability or aesthetics. If we manage to aggregate the vector to a single preference relation \(\succcurlyeq\), then \(\succcurlyeq\) represents our total preferences, or, as they are also called, our “preferences tout court” or “preferences all things considered”.
