What is Length

One does not only talk about the length in inches of this sheet of paper but also about the length of this sheet , about length in inches and about length. A clarification of these and related concepts results from a combination of the theory of the length in a definite unit as a fluent , developed by one of the authors, with the other's concept of 2 -place fluents. The length ratio L is defined by pairing a number L (α, β ) to any two objects of a certain kind, α, β (in a definite order). L thus may be described as the class of all pairs (α, β ), L (α, β ) for any objects α, β of the said kind. Length of this sheet and length in inches are specializations of this 2-place fluent
