Queen Elizabeth I of England famously wore a red wig, tightly and elaborately curled in a "Roman" style, while among men King Louis XIII of France (1601–1643) started to pioneer wig-wearing in 1624 when he had prematurely begun to bald. This fashion was largely promoted by his son and successor Louis XIV of France (1638–1715), which contributed to its spread in European and European-influenced countries. Perukes or periwigs for men were introduced into the English-speaking world with
Word and Object notation, Quine has eliminated all singular terms other than variables. This greatly simplifies his logical theory, in the sense that there is economy in the roots of the theory: there is a very limited number of elements. In some situations, however, short paraphrases are very useful, for example in mathematic deductions. For these cases, Quine introduces "definitions": we can define singular terms relative to the canonical notation. In that way, we can still use singular terms, without having to include them in our theory. In the last paragraph of "Word and Object", Quine asks the question why, in a book
