Lecture notes of a block course explaining why quantum field theory might be
in a better mathematical state than one gets the impression from the typical
introduction to the topic. It is explained how to make sense of a perturbative
expansion that fails to converge and how to express Feynman loop integrals and
their renormalization using the language of distribtions rather than divergent,
ill-defined integrals.
