But I don't want to condemn mathematics, since doing so would be engaging in a particular type of methodology. I don't much admire laying down methodological taboos, telling your colleagues the right way to go about things. I have always been a bit dismayed at Mises's a stern line against mathematics in economics. In general, I think people ought to be more modest in their methodological sermonizing. Just because one theorists doesn't apply certain methods doesn't mean they should be taboo.
Mathematics can be a good way of conveying some ideas.
With some concepts, you have to keep hammering at them to get them across to your students. The idea of maximizing utility under constraints should be done with words, graphs, and mathematics. Three ways are always better than one. To really understand these topics, you've got to go over them several times while using a variety of techniques. There are plenty of methodological taboos which are never even discussed.
