    Title: Factorization in double categories and Kan extensions.

    Abstract: Fundamental concepts of category theory can be expressed as
    factorization properties in the double category of categories.
    I will first present the cases of adjoints and companions,
    and after the notions of Kan extension and lift.
    The comparison of these situations will illustrate how
    Mac Lane's claim that "all concepts are Kan extensions"
    depends on the existence of companions.
